Greetings all. I have a 08 S4 cabriolet and I recently purchased a used OEM navigation unit off of the auction site and I’m getting it installed next week.
A couple of questions. Will I need the code to get it to function. There was no information from the seller as to what the code is.
If I do require the code can I get it from a dealer if I provide them with the serial number of the unit?
Also, it came with a 2007 CD map. Is it possible to upgrade it to a more recent map and if so, information on where to purchase one that a 2008 unit would be compatible.
Thank you in advance
