Для подключения такого радио на eBay или aliexpress посмотрите переходник . Самый простой способ. Но вроде не будет работать джойстик на экране . Радио в BMW это же мозги авто . Для многих функций .
Hello dear. I have a Radio business. I extracted front signal to manage front speakers (sub under seats + doors) with a 2 channel and rear signal to manage sub with another 2ch amplifier. The issue is how to keep unvariated the sounds coming from parking system..in particular due low pass cutting frequency..obviously you are not able to hear sounds from parking system...any experience? Thanks in advance
Hello. I made all connections only through the radio.I did not touch under the seats, connecting the signals from the four speakers on the doors.Power and weight are there and everything works great.Perhaps you have a short circuit somewhere.
