I’m picking up a Leon ST FR tdi on Saturday to use for a 60 mile commute each day so will spend a good couple of hours in it each day. I want to upgrade to get car play for the live traffic and was thinking about one of the units that fit between the screen and mib unit or just fitting an aftermarket head unit. Who has fitted an aftermarket head unit, what did you install and what pro’s and con’s were there, did the sound improve and did you lose any functionality compared to the standard unit?
