I've had the Z130Bt in my 07 Nissan Altima for a few months now I can't remember exact but it feels like a year and all I can say making my 6 hour trips with the NAV are prominent. The street names don't show up all the time but at least it tells you where to go and exit with arrows but if you change the views you can see everything it just takes a while to get used to. To be honest compared to the Garmin, it's not bad it gets you from point A to point B.
The iphone/ipod/bluetooth integration is amazing. I love hooking my iphone 4s to it, makes music and phone calls so easy for me.
