Hi all, first post here, been a lurker for a while. My fiance has an 05 E53 with the standard radio/cd player. Several months ago, i spent a whole day trying to hook up a Grom. I hooked it up to the wrong wires, then finally found the correct ones, but could not get it to work. Long story short, i pulled the Grom out and re-connected everything in its factory manner.
The display will not turn on now. The radio plays music for about a minute, then turns off.
All fuses are good.
I read that i could have drained the battery down, and caused the car to be in transport mode (the thread i found has the same identical issue)
Plugged in my INPA software, and got into the radio. There is an option for (transport mode - on)(transport mode - off).
Selected off, expecting the display to come to life...nothing. Tried several times, re-checked fuses, still nothing.
I am at a loss, i am not much of a radio/electronics guy.
Any help would be greatly appreciated!
