I'm moving to a place I've never lived. I LOVE the '10 Mazda 3 GT with Tech. It has everything I could ever want EXCEPT a useful Nav system. I've gotta do a 24-hour road trip when I move and the Mazda can't even find POI while driving, which is going to suck! I was also looking at a 07-08 TSX. While it doesn't have as many tech gadgets, the nav system is fabulous, easy to use, can be used while driving, etc. Of course, it is also an Acura. I hate that it doesn't have push button start, but I guess I can live without it. There is also the Lancer which has push button start, a nav system in between the best and the worst but has crappy interior quality.

Anyone have any advice?

the Mazda 3 is the only one of those cars I would ever consider suggesting, my advice is to look away from the asian manufactiured cars and more twords European and american, I personaly prefer BMW. and a good Garman can help solve your other problem (infinity has the best Nav system I've ever seen in a stock car BTW
