In August I stupidly left the sunroof open on my 2015 Countrman S All 4. As my luck goes - a torrential downpour occured ruining the radio. The radio actually works albeit limited with no display. No manual adjustment and the v/c does not work and the auxiliary input does not work. My Mini dealer says it needs to be replaced. - tried to order one which has been on backorder since August - was told "the radio is being built" with no projected date of delivery. I searched the internet for a used radio unit and have found several used and rebuilt units. I hesitate to buy used - no return options etc. and the one company that repairs them has a poor reliability rating. I have seen several options to completely replace the radio with unit that fits into the opening - Android 10.0 - says that it replaces the stock unit - works with the steering wheel control. Any ideas experiences etc.
