Hi

Ive been noticing the following issue which hopefully somebody can help with

im my 06 zed ive got the standard bmw bluetooth kit installed in conjunction with nav.
Ive got my iphone 3gs paired upto it no problem

Recently ive been noticing that the call quality distorts i.e. gets increasingly crackly as the call duration goes on.
Until today, ive been having to hang up and call back and the call quality goes back to being 100% - but then it gradually gets worse - say 4-5 mins.
Today i tried something. On the phone, you can switch the audio source from the bluetooth to the phone and then back again - when i go this - call quality goes back to 100%

Anyone have any suggestions or advice as to what might be the issue here?
I havent tried another phone yet

cheers
Jamie
 
The only thing I can think of is try a different phone to see if its the car or the phone, My iphone works fine, just the receptions not great.
