Jason, I have the full tech package and I already had a hand held Garmin. As for the NAV system, I prefer my Garmin more. However, the NAV works well in the NAH. What I wanted the Tech package for was the backup camera and the energy monitor. I have driven NAH with connection package as well. I like the engery monitor as you can really see and appreicate what the computer is doing and were the power is coming from. That is if you like that sort of thing. The backup camera has helped me park and avoid backing into small objects.

This is a persoal matter and I suggest you take it out for a drive. Both versions and see which suits you. The energy monitor system is great entertainment alone on long drives and does help the driver maximize full economy. When I got into a NAH with just the connection, I felt I was just in a regular car and missed all the toys. your choice.
