I'm researching different Navigation Video Input interfaces and have found the following so far:

Nav-TV
Neo Nav
TVandNav2GO
GNET

They all seem to be about the same price except Nav-TV, which I have't been able to get a quote for just the hardware. The one that I like the best is the GNET (http://www.gnetcanada.com/navvideo-m..._nissaninf.asp) but I haven't heard of anyone using it.

Anyone have this or know of someone that does? It has all the same features as the others, but also adds an iPod charging port and a wiring harness so you don't have to cut any wires.

 

I've used and installed the TVandNav2GO in an 04 Maxima. Install was very smooth and interface was good. Can't say much about the others, but hope this helps.
