Skip, Skip, Skip

Trying to play a cd is useless. Every bump in the road, expansion strip, or crack in the pavement causes the in-dash CD player to skip. Does anyone else have this issue or is it just my unit? I know we all love the e90s for their tight suspension and would not trade it for a song played from start to finish, but really? It is painful at times, I know the run-flats are firm, but is it that? I have the logic 7 system in an '07 335i Coupe.



If this is unique to my car, is there an in-dash unit that I can install?



Thanks
