Hi all,

My question is related to re-installing the OEM audio setup in a 2004 3dr A3.
Curently it is as I purchased it, with a horrible JVC aftermarket head unit and what I thought was Bose but turns out probably not Bose.

Is it feasible to purchase a Symphony headunit and code from another vehicle and install simply or will I need a vagcom session to set it up.
Also, will a post facelift Symphony headunit work in an older car, and how much work is involved in installing a Bose set up? Is it just plug and play or will new looms be required etc...

Thanks
