Ok, so my Service writer arranged for the Roadside Assistance guy to meet me at a local mall this morning to clear the theftlock from the new NAV unit. The unit powered up and showed me somewhere in CA (i'm in NJ). As soon as I drove about a foot, it updated to my exact location. I didn't have to do anything. Also, the speed sensor wire must have already been installed because I didn't hook it up (there was a wire there already) and it works fine!
Here are some things I've noticed:
Radio does indeed sound 100x better than the base!
My Onstar works through the mirror, but the button on the steering wheel no longer activates the phone... it tries to activate voice recognition.
When dialing through the Onstar Phone, the number does NOT show on the radio like it did on the other one.
The 'drive while watching a DVD' trick does NOT work.
Beaming my contacts from my iPaq worked w/o any additional software.
Unfortunately, my computer crashed and is still being loaded back to normal. Once I finish that, I'll post the pictures of the completed product.
It was a VERY easy project... especially if you don't need to go after that speed sensor wire. I did break my ashtray through and need to have it fixed (spring release tab popped off).
It feels like being in a totally different car with the NAV! I didn't realize how big a difference it really makes!!!!!
Thanks especially to TOMM for all the help!!! He made the install a million times easier for me!
The first time one starts up any GPS receiver, it takes a few minutes to get a fix (called a cold start). It needs to start cycling through satellites until it identifies four. After it sees the first one, it starts downloading the almanac which has the positions of all 28 GPS spacecraft. It takes three for a 2D fix and four for a 3D fix. Once the Nav calculates your position it stores it locally, so from then on you have a 'warm start' which gets your fix much quicker, since it knows which satellites to locate overhead. In the CTS, it is likely continually powered (the GPS receiver) which means it keeps track of your position continuously.
You shouldn't get any voice inputs or audio directions with the Nav unless you install the wiring for those functions. Miscreant is the only one to date to do this. I've got harnessing made, but need to get off my butt and identify terminals for the amp and the VIC (OnStar box) to complete.
So your VSS wire was already in the harness to the radio? Cool.
