Hardware for RaspControl system

[Bahamajoe]

Hello,

i'd like to make small summary of the HW neccessary i intend to use for the RaspControl in my E39 530d (sedan, facelift, 16:9 navi, BM24 radio, phone) and remarks for some of them.

Main unit
Rapberry Pi 3 - i have seen on the forum that some people use it so i suppose the RaspControl works on that too. Advantage is built in WiFi, bluetooth (although it seems the range isn't enough so the dongle might me necessary) and more powerful SoC compared to Pi 2. Disadvantage is higher SoC temperature so additional cooling is welcomed.

Pi case
Because of the higher SoC temperature, i'd like to use some sort of cooling case. Probably Flirc case but with some bigger heatsink fit in which would stick out of the case cover. I'm afraid of the plastic covers being too soft for holding up the heatsing in the trunk. Do you know about some other case which could be suitable for putting on such a heatsink? I don't want to use a fan because of the noise.

USB sound card
No discussion there, Behringer UCA222 is the choice to proceed with.

iBUS interface
IBus-Interface - USB, no discussion there either.

Power supply
I have a question mark here. According to your recommandations on the main site, you use cigarette lighter supply with 2 USBs. The question is - don't the abrupt turn on and offs damage the Pi over time? Have you guys had any issues with the Pi itself over time? Since i have no cigarette lighter socket in the trunk, i'd have to buy also a socket etc. This alternative you propose isn't sold anymore. I have found Mausberry 3A supply which communicates with the Pi via GPIO and enables soft turn on and offs. It costs around 30€ though. Does it worth it in your opinion or is there any other alternative?
I got a normal 12v to 5v converter from Goodluckbuy. I think any converter can do the job, it depends on how you want to set up your system.
My system always get a hard shut down. Had no problems in 2 years (Using also a rasp in the living room, which will be siwtched of almost every day). You can also switch of over the menu.

Cables and wiring:
Video - you suggest such a cable with 4 poles mini jack and cinches. So the mini jack goes directly into the Raspberry and the ground and video are supposed to go on pins 13 and 14 of the white plug on the videomodule Right.

Is there and specific cable to do that or you pretty much hard wire such a connection? I prefered to disconnect everything if necessary from the car, so I used a Chinch to MQS lock cable 

On that case i suppose that the videomodule is gonna be thrown out of the car and replaced by the Raspberry right? Partly right, if you only want to use the rasp for actuate the hardware of the car like mirror moving or tip blink, then you do not need the tv module (Take care, you have to do all the necessary adjustment over a TV or over the file system), but if you want to use the  On the pin 17 of the blue socket we get the GPIO pin 27 through resistor 100Ohm This one is the input signal for switching the headunit to the rasperry when you change the mode to cd changer.

Again, is is possible to buy a corresponding blue plug to make it in a way that you can disconnect it easily and connect back the videomodule? Better to use MQS plugs, the blue and white connector are empty, if you don´t have a rear cam Or are the cables just added to the existing wiring as a branch? Can easily added with the MQS 

And finally - R-Cam is rear cam i suppose Right. In case this one is present, where is it connected? See this topic, where harry descriped it, there is a pdf for wireing (VM means Video module)

Audio - pretty much the same as video, are the cables hooked up on the existing lines? Since i have seen on videos on youtube, the original radio still works so i guess it does not go out? Most of us using the CD changer plug for IBUS and Audio, but you can also direct connect it to the quadlock plug of the radio module.

iBUS - since i have a phone which doesn't work anymore these days, i guess the iBus can be connected from phone of maybe even better from the changer which i don't intend to feed with tenths of CDs and anyway there is a need for some space on the trunk so sacrificing the changer seems as a must. IBUS can be collected almost everywher in the car. Someone invented the idea to buy a not working CD changer and install everything inside, so it looks like OEM. The topic can be found here

SD card
Probably SanDisk 8GB as you suggest. It serves just for operating system/RaspControl image? So the 8GB should be all right. Yes



Your comments are appreciated. I'm sorry for such a long post but i try it to be as much complete as possible in order to have some sort of "manual" in english.

Hope you can use all the informations.
