2012 Mini convertible, radio/nav died, so replaced with a nav radio unit from a 2012 mini. Everything works, except Nav with starts up for 30 sec and goes back to nav icon and will not open Nav anymore. Dealer stated it is a bad hard drive in the new used unit and said they would order a new one for $2100. Passed, but wanted to see if anyone has had this happen or thinks this is a real possibility instead of a upsell.

Thanks
