In my opinion, the battery overheating may be a bigger problem, but I have not read the cell specifications yet.

LiIon cells can be discharged to a temperature of 60 ° C, and charged up to 40 ° C (the temperature of the cells, not the environment)

The option of removing the tablet was taken into account, inter alia, due to the battery, not the matrix. The console in a car left in the sun heats up to over 80 ° C. Even if the matrix was padel, I would exchange the nexus for another for a few words. If the battery caused a fire, the car would go up in smoke. Everything is under supervision while driving. However, the most important argument was the possibility of keeping the tablet function when I am not using the car.

When it comes to CAN, I mainly mean steering wheel signals.
I have already managed to capture them, now I have to fight the Alpine DSP interface.

Hello, could you say something more about intercepting signals from CAN ? I am fighting a similar project myself, nexus 7 in Vectra C where the steering wheel signals are also CAN. Regards Sigul

Hello, I tried something similar in the classic Dodge Ram 1984, because the mileage counter, so I figured out that by installing a tablet-samsung galaxy 3, with GPS support and navigation with the addition of TorQue, I fixed it instead of the meter, just in front of the steering wheel. I left only the indicator lights and lights. Everything looked neat because the casing was printed on a 3D printer. and unfortunately the partner with such a non-certified meter did not pass the technical inspection. It's a pity because everything worked on android and I generally used ready-made solutions programmatically. because the tablet had OTA options, I connected a webcam to it and recorded it with the Black Box program.
when I find photos I will share it.
At the beginning she was sneezing because handling the touch by the steering wheels could have ended in an accident, but I solved it by trackball - it's such a bigger mouse.
ps it really was so close that he had a checkup - only the diagnostician was too inquisitive

How to solve the problem of battery overheating? I have a tablet in Almeria n16, in the upper part of the cockpit, when it's outside at 25 degrees and it's sunny, the tablet goes crazy, overheated battery, and punishes to disconnect the charging, after a long time it turns itself off and resets non-stop until it is cold. Is it possible to make some thermal insulation or is it better to remove the batteries and make a battery accumulator from a permanently connected voltage? Umnie, I have it done with the tablet after disconnecting the ignition switch disconnects the charging, which results in the screen blank.
