Up until yesterday, I use to use those casette with the 3.5mm jack adapters to stream music from my phone. The casette will go in but within 5secs, it will automatically switch to a fm radio station. I've put a new casette in to eliminate casette fault, however problem is still there. It's the Casette/6CD inter grated symphony which is powered by a Bose amp (oem setup). Is this a common fault? Is there a repair for this?
