I figured I would check to see if the same screen that I have in my Accord would fit in the truck. According to the specs on their website, the overall dimensions of the screen are 165mm wide and 100mm tall. So I cut a piece of cardboard that size and it dropped right into place, like a glove. The only thing I am worried about is all the cables that go to the control board. Power, HDMI, RCA Video, and the ribbon cable to the display. I messaged the seller on eBay, and they responded that a custom cable between the board and display would require tooling and a minimum order. I don't think they understood that I just want an extension, so I can have the display in the cubby, and the control board underneath. So I messaged them again, trying to make things more clear. I also asked about the number of pins and the pitch of the cable, maybe I can find an extension myself, or make one. I know Adafruit sells an FFC coupler...
It's amazing how the bezels on the official screen make it so much bigger. That piece of cardboard I cut fit like a glove.

I ordered the screen yesterday, along with a little junction board with a 200mm FFC extension. I also ordered the Capacitive Touchscreen with it. Since I ordered them together, they'll mount the touchscreen to the display for me. www.ebay.com/itm/7-inch-TFT-LCD-Display-w-HDMI-VGA-Video-AV-Driver-Board-1024X600-Raspberry-PI/292355591718?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649www.ebay.com/itm/50Pin-To-50Pin-ZIF-0-5mm-Connector-Adapter-Extension-Flat-Cable-FFC-Extend-20CM/153074620160?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649My only concern is that I hope that the 50 pin FFC cable does not flip, and I need a B Type cable instead of the A Type. I hope with 8 inches of FFC extension that I'll be able to get the control board under the center console. I also told them to ship a Video extension and a DC power extension, as that will improve the flexibility of mounting the board. It has headers on it for extending the RCA input and the DC power jack off the board so I'm not trapped for space having to fit a plug into the board. The only plug that has to plug in directly is the HDMI. With the camera's RCA going right into the board for the screen, I won't have to modify my camera, or mess with any GPIO to turn it on. The screen will just switch to the RCA input when the camera powers up. I can make it so that it not only powers up when I'm in reverse, but maybe I'll add a switch, so I can do it on demand. I just won't see the Pi's screen while in reverse, but that's not a big deal. I still need to order an extender for the touchscreen. Looking at the datasheet at buydisplay.com, it looks like a 6 conductor 0.5mm pitch FFC. Still no timer relays. Next Tuesday is the latest receive date, so I suppose next Tuesday evening I'll complain.

Yes, they're not my favorite, but they do have some good qualities.
For one, they are flat, which will allow them to pass between my center console and the dash without making any mods to my truck. I can have a plug go between the truck and the center console with 12V, Ignition, Ground, Reverse, Power antenna, (Or the power on signal from inside the Aux module), and the RCA reverse camera signal. Everything else can be attached to the center console, making the system easy to remove and work on.
I sent a complaint to the seller of the timer modules on Ebay. I told them I want 4 of them shipped out right away, with tracking. Also that other stuff I ordered from China at the same time as my original order arrived in 12 days. It shouldn't take 11 weeks. Their current price is still more than I paid, $5.90 each for 4 compared to the $0.90 each I paid.
Of course the last time I had a problem with Ebay, other than the little Bluetooth modules that were supposed to have a mic, and didn't, was the load tester. It was a fake, and the seller said that they had some that were not fakes, and they would send one. Well, while waiting for the second one, that ended up never actually getting sent, the time expired to complain on Ebay, and I had to go back to Paypal. But Paypal covers for 6 months, so it really wasn't a problem. It's just that I had to take the fake one to the post office, pay about $30 to ship it to China, and Paypal credited me.
It looks like the screen, and FFC extender I ordered is in the US and has passed customs.

I saw 8 GB pi's are now a thing. I'm not about to go buy one yet, but it's nice to have the option.

Youtuber ETA Prime did a video about "Raspberry Pi 8GB Review - Should you upgrade?"
He got his memory usage up to 7.8G. He had the following open, all at the same time.
1. 3 copies of GIMP, each editing an 8K, 8MB photo. 2. Blender doing a benchmark 3. Rendering a 1080P 60fps Video in Oneshot 4. 31 Tabs in Chromium opened up to Youtube
I think for $75, I'll hold off.
I'm not saying it wouldn't be nice to have, but at $75, and my typical use case for a Pi, I don't think I need it.

I complained to the seller about not getting the timer relays. Of course he responded with, "How about we give you a refund and you leave positive feedback". I said no, I want the items, shipped now, with tracking. You can't tell me it takes that long to ship from China. Reputable sellers, like buydisplay.com have it figured out. The screen and touchscreen that I ordered on May 27th have left Illinois. I imagine they will be here in a few days. It only took a week after ordering for them to get from China to IL. Actually they didn't leave China until the 31st. With the last batch of ordering, all the other stuff only took like 12 days. Something I saw on Amazon that was interesting, not that I will order one: www.amazon.com/dp/B07Q837744A single DIN car stereo, with 4.1" capacitive touchscreen, Bluetooth, Steering wheel mount IR remote control, wired input for factory steering wheel controls, Sub out, Backup camera (camera included), Microphone (looks like it has an internal and external mic), Separate video in and out, RCA audio in and out, Dual USB on the front (1 for data, 1 for charging), 3.5mm Aux in, Micro SD card, FM/AM/RDS, and a rotary volume control. All for $54. The only thing I see some of the others do that this one does not is phone screen mirroring. But those don't have audio and video in and out, and no sub out. And of course, it's a cheap Chinese radio.

I woke up this morning to an email saying that I had gotten a refund. In every piece of correspondence I sent them I clearly stated that I didn't want a refund. I wanted timer relays.
I've responded telling them that a refund is not what I wanted, send me 4 timer relays or I'm going to Ebay, and leaving negative feedback.
Also that I'll tell their mother.

Going on the assumption that I'll get no joy from the Ebay seller, I ordered an FRM01 from Aliexpress. I picked a US seller, and I've been guaranteed to have it by the 26th of this month. There was a $2 coupon for first timers, so I paid a little over $6, free shipping. Man, Ebay US sellers were about $16 and higher. Sucks that it was $0.90 in the middle of March.
I guess we'll see what happens.

The 50 pin FFC extender arrived on Monday. No sign of the screen or the other extender yet. Tracking says that it arrived in Indiana on the 4th.
And although Aliexpress said it was shipping the timer relay from the US, I think they were lying. It says it was shipped, but the tracking is worthless, it shows nothing. I show that it was shipped on the 9th, and it should take 9-15 days. I was promised it would be here by the 26th. They says if it does not arrive by the July 1st, I can apply for a refund.
I think the Ebay seller got notice of my complaint about them through Ebay. He sent me a message saying that they would check with their partner, and get back to me. I responded, thanking them, and telling them I was looking forward to their response. The next day I got another message, a copy of the first message. Again, they are just stringing me along. I'll probably never hear from them again. And so much time has passed I can't leave negative feedback.
Open Auto Pro 9.0 has been released. I sent my email with my order number last night, and got my link this morning. This version is not a massive change:
Change log:
- Support for German, French, English, Italian, Norwegian and Polish languages
- Upgrade to PulseAudio 12.2
- Setting of handedness of traffic for OpenAuto Pro interface
- Notifications are now displaying on Top Bar when Android Auto or Mirroring projection is active
- Bug fixes of Hands-Free calling profile
- Emoji improvements
- UI improvements
- Stability improvements
Anyway, I downloaded it this morning, and I'll try it out.

I guess I checked the mail too early yesterday. I checked it later than the normal time, and there was nothing. This morning I had en email saying that my screen had been delivered. I went out and got it, and opened the boxes. The seller, buydisplay.com really went above and beyond with this shipment.
They attached the capacitive touchscreen as they said they would.
I had requested an FFC extension to move the control board further away from the screen, but I was told that they did not have anything for that, so I ordered another one from a different seller. To my surprise, in the box attached to the control board was a 30cm FFC extension cable and extension board. Cool. And Free.
I asked them to include both the DC power extension cable and the video extension cable. Normally if you order on their website, those cost about $0.20 and $0.56 respectively. I asked about them, as when ordering on Ebay, those do not appear to be options. They offered to throw them in for free, and they did.
According to their website, if you order directly from them, they are not currently offering free or economy shipping, you have to go DHL or Fedex. Ebay prices are a little higher overall, but not enough to offset the shipping costs of DHL or Fedex, so it was better to order on Ebay.
They also did well when I ordered the screen for my Accord. I had made the mistake of ordering the screen that included the Mini HDMI board. It does not have any alternative inputs. I wanted the Video input in case I decided to add the backup camera. When I inquired about getting the larger board separately, they were able to create an Ebay listing and invoice me for just the price of the board and shipping, about $17.
It took 3 weeks for the screen to arrive. And their customer service has been great. I'll have to hook it up and try it out, and see how it looks sitting in the truck console. Once I figure out where everything is going to mount, I'll need to get a Micro HDMI to HDMI cable for the Pi, length dependent on where things mount. For now I have a 6 foot cable to test with.
EDIT: Wife saw the mail carrier go by again. I checked, and the FRM01 timer relay showed up. Maybe he dropped it in the truck, and found it. That was my 3rd trip to the mailbox today.

I got the screen hooked up today, and the 50pin extension works great. I am still waiting on the 6 pin extension for the touchscreen, but I still was able to hook it up with the regular cable.
I can't seem to get the input to switch to the AV1 or 2 input when my reverse camera turns on. I went through the menus, but don't see anything. I sent a message to the seller for how to do it. I see there is an Auto, but it looks to be just from VGA to AV. Also, on the plug for the extended AV inputs, Pin 1 is labelled ACC. The manual says that it's Voltage Input 12V for Reverse Sensor. The problem is that my plug does not have a wire on that pin. In fact, it's a 4 pin plug, not a 5 pin. So there are 2 Video pins, and two Ground pins. I can see the camera if I plug it into either AV1 or AV2, and change the input to that selection. I just can't get it to automatically switch.
I'm still cheating by using multiple power sources. I've got a 12V wall wart powering the screen and another wall wart on the USB hub. I'm using a USB-C cable to an AC powered 5V adapter for the Pi. I've got the reverse camera powered with a 12V bench supply.
I just tried hooking up the 5V 10A converter to power the Pi. I know the pin to pin jumpers I have are undersized to power the Pi, and with all the jumpers in series between my breadboard and the Pi, it would not boot. It came up to a screen I have not seen before. It was looking for the SD card and failing out. I disconnected the 5V I had wired to the GPIO, and tried the USB-C again, and there was no problem. Looks like I need larger wires, straight from the converter to the GPIO.

On our CARPC ver 1 the video card would automatically switch when that 12v line went high and then back to the previous input when it when low. What video card do you have?

7" inch 1024x600 TFT LCD Touch Display w/HDMI,VGA,Video Driver Board
There is no version number that I can see on the board. It does say "2AV-1VGA-1HDMI-TTL-50PIN-LVDS-ACC" and HDMI-1.2. So maybe version 1.2.
I don't have an ACC wire. There is a 4 pin plug plugged into a 5 pin jack. So the pin is available, I just don't currently have a plug for it. I suppose I could solder a wire to the bottom side of the board.
On another note, earlier today I hooked up and tested the FRM01 timer module. I set it to Mode 10, which is time delay off after the trigger input goes low. I used that and a couple diodes. Now, the ignition turns it on, it powers the module, and turns on the trigger. When the ignition goes low, it stays powered from the battery connection through a diode. When the timer expires, the whole thing shuts down. No phantom current draw. It's a 10A relay on board, so no problem powering the 5V 10A buck converter, even if it takes full 5V power.
I think I need to draw up a board to send to JLCPCB to hook up all this stuff to the Pi, and get full current to it.
