android

[mikebike7]

I have bought an Android gps radio for my BMW e87 series 1, but am now selling it. So i am installing the Android radio/GPS in my 911 from 1974, but the Android won´t turn on at all even if there is power on the yellow + and red ignition and black-? Can it be I need a interface or a canbus for it to accept the power from the old car?
Hope someone can help.
