I don't want to mess up the Bose system but I need a head unit that I can either play BT audio to or that I can plug an aux cable in at the very least. What are the options nowadays?
Is that an FM transmitter? I'd rather not use one for quality reasons to be honest.
If I replace the Symphony II with a double din aftermarket HU will it be an issue to connect to the BOSE setup or can you get ISO cables that do the job properly?
I use a little plug in unit that goes into the cd changer socket. It's made by Apps to car. Cost around 50quid took 30 min to fit. It has a bluetooth connection plus a 3.5mm jack. A bonus is you can also plug a memory stick in also. On ebay. Hope this is of help.
