I'm looking to upgrade the head unit in my 2008 9-3 and I'm really overwhelmed by all the information I can find on the topic. I got a couple of questions:
1. What adapters do I need? (Planing on buying a Sony HU) All the adapters I found were for 4 channel audio amps (are that enough channels for the prestige 300 system?)
2. Is there a way to fit the iDatalink Maestro RR to my 9-3?
Thank you in advance.
