Troubleshooting

I’ve had plenty of issues while trying to figure this retrofit out…hopefully if you run into problems, these will

help:

NO AUDIO – This is entirely normal if the car hasn’t been coded yet.

NO DISPLAY – Make sure the fuse is not blown. Also, if the bus wires are not hooked up, the CID will not know

when to power up.

NAVIGATION IS FAR OFF ACTUAL POSITION – Check to make sure your system is getting an antenna signal

from the GPS antenna. I do this by checking the “Current Position” menu….if it doesn’t display an altitude or

displays “----“ in the altitude field, check your shark fin and new wiring to it. (My brand new antenna cable

from BMW had an internal direct short.) Make sure that you’ve hooked up the lead to the blue

fakra

connector. I’ve also been told the TCU can cause conflicts with the GPS location prior to it being coded for a

navigation system install.

NAVIGATION SYSTEM WON’T PLAY DVD’S - The navigation system will not

play DVD movies! (Yes, it will play

DVD-ROM’s, but ones with MP3’s on them.) If you want your I-drive system to play movies or show video (i.e.

backup camera, video games), you need to add additional hardware.

WHICH DRIVE IS WHICH? - The Navigation DVD goes in the bottom drive, audio CD in the top drive.

WEIRD PROBLEMS – Check and re-seat fuses! I know it sounds stupid, but I had a strange recurring i-drive

controller issue due to a loose fuse.

Notes

Hopefully, this D-I-Y guide was helpful – whether helping you to make an informed decision about doing this

retrofit or as a guide. If any of you do this retrofit, feel free to send me pictures you have taken (especially of

connector x11003, junction x9331, or other pictures/details I may have missed.) I will put them in this retrofit

doc for others to benefit from. Forward them to:
