Hi soon will be an owner of an a7 just wondering if there is anybody who can help retrofit a few things. I'm located in Birmingham so surrounding areas will pay parts labour tc.I will help as much as I can but I have no experience at all. Has the tech pack advance with mmi high I think which has google options and it's a 2013. Retro would be reverse camera maybe front depending on costs. Codings and anything else we can discuss.
