| Depending on how old your 328 is, u may need to buy a link lead that will connect to your BMW audio harness convertin it to a standard ISO connection. You may also need to buy an adapter for the coax plug, depending on wat type Pioneer use on their systems...
Best bet, take the old head unit out 1st and have a look at the audio harness connectors to see if they're already the ISO type, and check to see if the coax will just plug straight in...
It'll either all plug straight in or u'll be in 4 a trip 2 Halfords...
Good luck...
