I just put in Eclypse AVN 6600 Nav system into my hummer and I got to say it is the baddest NAV I've ever seen.

Also got an Autopage alarm and it is pretty cool too. Remote start and 2 way LCD so you can see what is going on. Also if your alarm goes off, your remote goes off too, so you know when your alarm has been triggered

Still trying to build more and more on top of my H2, only had it for about 3 months.
Anyone else got the AVN 6600 or Auto Page alarm?
