I probably use the CD player, located in the glove box, more than anything else for  ICE, but every time I need to change a disc I wonder at Audi's logic at making it such a difficult job. Yesterday I was the passenger and found it impossible to access the player. I guess all other times I've changed as the driver I just leant across and did it. Obviously out of the question if you are on the move!

Only way round it would be a 6 CD stack system  located  somewhere accessible. 

Does anyone know whether this can be retrofitted ? or any other good ideas.

Thanks Mike

Hmm could it be moved to the armrest? Or does your A3 have any Cubby's like this  on my A6. 

In this cubby I'm going to be fitting a CB radio 😉

Thanks Steve for response, I don't think there is anywhere suitable and I can imagine some wiring problems as well. I'll suss out a stack system and see if anything comes up, probably silly money if there is OEM system. All best.

No probs at all.
