Hi,

i have an e60 with business navi.
my bluetooth keep reconnectiong .. even if he stay for 1-2 min connected he dont find network...(no service)
audio.. radio/cd working some min and after its stop working or its like i don`t have signal... even from cd's... some disturbing noise..
voice commands not working at all now...

it was all ok until some days ago when i made a call and after all wasn't working correctly ...

i made 3 diagnostics.. even at dealer... all from with different opinions..

dealer - bluetooth module its broken (but.. if bluetooth module its broken why i have problems with audio .. cd/radio?)
another diagnostic from some1 else - MPM micro power module or something its broken
another diagnostic - mask unit broken

any help its appreciated.
