I was reading a few threads but did not see the answers i was looking for. i have an 04 6mt coupe and the GPS is definitely outdated, i know that the dealer would charge me an arm and a leg so i was wondering what my options are. would i be able to update it with a disc from a 2012 G37 or does it have to be a G35 disc . im thinking of just buying it somewhere...... please advise. Thank you.
