I've found a few answers I need, but now stuck. Got a 2004 with Symphony 2. It died after two days of having the car. Sounds like a bag of nails is stuck inside.
How do I know if the system is amplified? (it's not Bose)
I plan on upgrading the stereo with a single din Bluetooth unit. Like I've done in the A4 (massive thread somewhere)
Any help would be great.
