I saw an Overlanders video which led me to the Hisma videos and then to OA. I am starting down a path on my wife's first gen Mini now. Luckily she has the chrono pack (speedo on steering column) so I can take out her center gauges and replace with a sat nav unit from another Mini. My wife really prefers her car to retain a factory look in regards to the setup so there are a few challenges I'm trying to work through.
1ST - I can't use the Rpi official screen. The original screen in her car is only 6.5" so I ordered a screen, capacitive touch panel, and lcd driver from AliExpress. A little dremel work and JB weld and I was able to modify the screen setup to match the original. The driver board has been a bit of a pain. Board 1 was a dud.... so I ordered another (arrived 3 weeks later). Of course, I can't adjust the brightness through the software, so I need the physical knob from the original Mini HU to be able to adjust the back light brightness (which she prefers anyway). For that I will be using pwm through the PT4103 (as found on stackexchange link below). I know I've got the pwm working by testing on a series of leds, but can't seem to get the board working. Could have been a poor soldering job on my part though because last night the PT4103 started smoking... (waiting for board 3 to arrive in 3 more weeks... slightly different model this time ).
2ND - I'm exploring options for an OBDII usb solution to plug into the Rpi and displayed on screen (link below).
3RD - Since the Mini is an 05 it uses the outdated indirect TPMS system. So I'd like to find a way to integrate TPMS into the Rpi using rtl-sdr (link below). Not a must, but would be really nice to have.
4TH - The puny little steering wheel doesn't really have any buttons. I plan on trying to figure out how to make those work and what I can use them for. There is a + and - for volume control, also an up and down arrow for I don't know what, as well as a phone symbol and a button printed R/T.
5TH - I'm trying to keep this all contained in the little box behind the screen from the original unit.
6Th - Wondering how the new android auto look is going to affect OA
This is a work in progress that I hope to have completed in the next 2/3 months in my spare time.
