Another NAV question

[LV_H2]

I was busy last week and just got the unit installed today. I haven't had a chance to put it thru it's paces yet.

First impression, excellent ipod interface, some issues with location on NAV. I have been reading that the NAV system "learns" over time. Other issue is that you lose the ability to control Onstar volume.

Regarding VSS, my understanding is that it is only necessary for NAV when you loose GPS signals, and not needed for normal navigation. (AVIC411.com forum). I am not even sure if my installer hooked it up with VSS or not.

I'll give you an update in a few days.

Just got done with my installer re-doing the connection on the AVIC D3 in my 2007 H2.

The VSS was obtained from the Factory 10 Pin connector at the Radio.

The wire is Dark Green/White Stripe. My 2007 had TWO identical Dark Green/White Stripe at the "E" and "H" positions. According to my installer, the models previous to 2007 had one such wire at the "H" position which should be used for VSS. On the 2007, both are VSS, but the installer was recommended to use the "E" wire. We hooked up the Dark Green/White Strip "E" wire, and it works perfectly.

(The installer's assistant did the first install).

Good Luck.
