Another NAV question

[GasGuzzler]

Hey Las Vegas

How did the AVIC-D3 installation go? I am doing the install myself. I am curious - where did your installer connect the speed sensor wire? There are 3 possible places that I know of - 1) In between the battery and the engine block 2) Green/white wire on the 24 pin plug goin to the instrument cluster and 3) On a plug going into the (some) stock radios.

I am curious how your installer did it.

Thanks,

I found an installer who does the work for my local Hummer Dealer and is very familiar with the H2. He recommends the Peripheral adapter, and will be installing an AVIC-D3 for me tomorrow. I use ONSTAR, and I am mainly looking for the iPod interface, which seems to be a more direct connect on the D3 than on the Z2.

I am having mine done "thru the dealership" just in case there are any issues!

Thanks again for the feedback.

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.
