I tried inserting the "grey" micro sd card into the "white" slot to see what would happen... NOTHING! Apparently these micro SD cards are vehicle specific. Before I goto the dealer and get upsold on everything, what else am I looking at? Someone had mentioned the cost of both the card and programming??? It's understandable why these would be vehicle specific but it also pisses me off that someone took it and it won't work in anyone else's vehicle. I see Lexus micro SD cards for sale on eBay for $80 but thankfully I had one to test out before I wasted my money. I fully understand I have to goto the dealer but I just want to know what I have to pay for an approx cost. Any guidance much appreciated.
