Concert 2 Bluetooth upgrade

[tweedy]

Hi all, new here but not to my Audi (b7 2.0d SLine). I've got what I think is a concert 2 double din, it's got the bose sub in the boot. I'm currently using an fm Bluetooth transmitter, but the quality is pants and I keep having to adjust the frequency on my daily commute. I would really like to either upgrade the head unit, which I'm lead to believe isn't easy with the Bose system, or add a Bluetooth adapter. Any advice or help in finding something decent and compatible with be great. Oh and it doesn't have an iPod dock.

Cheers guys

I think it's the bose amp which causes the issue.

That's what I had read, but I can't seem to find a solution to it, other than rewiring it all, and I'm not liking that idea
