My father has a new RS4 Avant (B7) and had successfully linked his Samsung mobile into the factory-fit Sat Nav/MMI system via Bluetooth. However he just got a new mobile, also a Samsung, which is refusing point-blank to "find" the car by bluetooth link. My Motorola V3i is also refusing to "find" the car. However, if we stick a simcard back in Dad's old handset, the car and phone happily link up.
This is weird and very annoying. We've read the handbooks of both the car and the phones until we're blue in the face and cannot make either Dad's new phone or mine link up with the car - even though the two phones will find one-another happily enough!
Does anyone know why this might be and how to fix it?
