leebA4

Hello all, This topic has probably been dealt with before so apologies for the repeat if that's the case. So, I want to upgrade my interior to the S Line black leather sports seats, My A4 is a 2012 B8 saloon model, is it as simple as it appears i.e. find an interior that I want from a similar year car and unbolt the old interior and refit the upgrade interior and bolt into the existing fitments? I don't want to change the door cards as they are all in good order and black so they will match the interior so its just the front and back seats that I want to change. If anyone knows where there's a set of the S Line front and back leather seats in black that will fit my A4 please let me know. Thanks in advance for taking the time to reply.

Hi all I need some advice please I've just bought an A6 C7 SE but it didn't come with the nav disk or SD card. The dealer price is just bonkers but they said it needs to be coded in and they were the only ones that could do it. So my question is where can I get a working version of the nav pack and do Audi really need to program it ? Thanks in advance
