Hi Guys,
I have recently fitted a Highway 400 digital radio unit. It is a wireless unit and integrates with the BMW car hifi via a FM frequency. It also connects to my phone via bluetooth so i can stream music. My problem is that during radio play or music streaming there is a crackle. This does not happen when on a call via the car bluetooth connection.
I am wondering if it is bluetooth interference, or FM interference, i have tried shifting the frequency pairing via FM but nothing changed with the crackle. Engine speed has no affect on the crackle either.
Any suggestions as to what could be the cause and how to rectify it?
