I bought this 2010 Audi s5 and the MMI doesn’t work. I bought it like that.. wondering how much it’s gonna run my pockets. I checked the amp on the right side of the trunk it has flaky white blueish stuff on it. Seems like maybe it got humidity? Idk I don’t want to take it to the dealership and get charged an arm and a leg. Kinda hoping I can figure this out outside the dealership. Any Audi technicians in the Ohio area? Pls help I want music!!
