Radio and Nav Voice No SOUND
 

I have an X5 from 2001 and sometimes my radio, nav voice and K7 have no sound. the cd always have sound but the radio only work sometimes. To work the radio i have to close de rear door with strong and put the system sound in mute... then it works. Can you help me please???

Anyone can help me PLEASEEEEEEEEEEE

Not sure if my recent problem was exactly the same as yours. Sometimes (very regularly) the audio would mute - radio, cassette, cd, tv, nav. The phone and voice control still had sound when the others would not. Sometimes (but not always) pressing one of the radio preset buttons would get the sound back for a while.

I thought the amp must be faulty so I decided to take a look. The amp is located behind the LHS panel in the trunk under the CD changer. I removed the CD changer but realised a fair bit more dismantling was needed to get the amp out and I didn't have enough time. I unplugged the wiring harness from the amp (which was accessible) and checked for any signs of corrosion on the pins but all seemed ok. I put everything back and what do you know - the problem has stopped (touch wood!).

Perhaps it was just powering down the amp that reset something or there might have been something dodgy with a connection that got corrected by unplugging and refitting the connector.

Give it a try - it might just work for you too.
