I have mdl 4EN52Z1230 and it says my maps are 23 months old. Every model I've owned in the past craps out at this point and I have to by a new model. Why you ask, because the TT Mydrive Download does not work for W7 Vista 64 bit. Too many errors upon trying to install that crappy program. BUT, what is the claim about free updates I have always heard about? Granted, megellan and other GPS programs are junk. I know, my 35K jeep has a useless GPS system and I got this unit on my windshield.
Why do I always have to buy another new model to get over this issue??? This is my 6th model over the years
