Would anyone be interested in helping me upgrade my audio system in the Z4? I don't have a clue where to start, but I do know the sound system is low quality compared to an E39 business system I had. The Z4 behind seat speakers are very poor quality.
have been reading some previous posts, but wondered if there were any plug & play upgrades for under £200?
