Got a question for any UK members.

I am trying to get a new stereo fitted in my A4 by Halfords and i need a Harness adaptor but I can't find out which one I need and Halfords couldn't work it out either. i need to know if my stereo is BOSE or not? Sorry if this sounds stupid but that's pretty much how I'm feeling today. Feel free to treat me like an imbecile

 

When the stereo starts up it should say BOSE. Also youre frondoor speakers will have a BOSE emblem on it.

 

Cheers mate, thought it could be simple and don't know why I couldn't find that out elsewhere. As it happens, an Audi dealer looked it up via my reg today (I knew it was still the original stereo) and confirmed that it's not BOSE and is in fact a concert stereo. Thanks for the reply
