It's got the 'standard' stereo; in dash CD, No NAV, not premium.
I have upgraded stereos in the past - using Crutchfield (I know you guys are probably shuddering at this) - but it was for a straight speaker and bass install/plug in.
I have'nt done anything on a BMW before and am electronically challenged. I was wondering if a bass addition is worth it and if its something I could do on my own - i.e. using Crutchfield install kits.
(This is a v low budget mod)
