X5 IBUS(?) USA Spec iPod Problem- With Necessary Details!
 

Hi, I'm not new to BMWs or their forums but I'm new here. To start off with, I DID search before asking this question. Today, I helped my friend try to install a USA Spec Adapter into a 2004 X5 3.0i non-DSP, non-Nav.

I disconnected the battery and hooked everything up, then reconnected the battery before I ran the wires to test it. It worked! Everything was normal, no extra lights, display was working, etc.

Fast Forward:

I ran the wires down the driver side and removed the rear bolster in the process, then tucked all the wires under the driver seat. I had to take out the under-dash (driver side) panel to run the wires for the AUX-input to his dash.

Turned the car back on, everything works, no extra lights or codes, sound, NO radio display? The radio track/next track, volume, power, etc. buttons are all unresponsive.

You CAN control the radio through the steering wheel and it will change mode when you insert a CD.

Disconnected the battery for an hour, the display still doesn't work. I tried unhooking the USA-Spec iPod and resetting the battery, and re-hooking it and resetting, and it did not work.

Sorry for the long message! Help?

I thought disconnecting the battery first was supposed to avoid this IBUS mess. :stickpoke

bump. Help please? :(

BUMPPPP!!!

Sure you didn't cut a wire from the I-Bus? When I installed an I-Bus device I did on error and everything was messed up.

What if you return your installation to original? Would that be possible for you on a temporary basis?

Good luck.
