    Re: Navigation while driving

    obxdiver, you are the man. I did this simple "hack" yesterday and it works perfectly. I opt'd to remove the wire connector from the plastic housing rather than clipping the wire, this took a few more minutes but I feel well worth the time. I will say fellows that my NAV unit took a couple of "short" drives to correct the 15 second updates. I only drive 3 miles a day.

    Thank you obxdiver!

    has four green wires on two different connectors and on both, one is solid green and the other is green with a black stripe down it. Did the guy give me the wrong harnes or what? I have looked and looked and no where do I see a green wire with a white stripe? If I have the wrong harnes, where can I get the correct one to hook up my OEM touch navigation. Thanks in advance!!!

    Mark, our 2005 has the green/white wire. Look at the picture in the beginning of the thread and match up the holes to your wiring harness, you should see the correct wire.

    I did like three times, I think he sent me a harnes for a non touch screen 2004 or so? Does anyone know if the old harness will work and if not, where can I get a new 2005 harness? Thanks in advance!!

    Click on the following link I posted those pictures back in 2005 They show the wire location at the instrument cluster connector and the radio connector These connectors are part of the factory harness Why would you need a harness? My truck had the factory am/fm radio When I added the navigation radio it is just plug and play after you removed the theft-lock. The only thing I had to add was the gps antenna. If you look at the pictures I posted, the Vss wire is the green with white stripe located at row A pin 4 in the instrument cluster plug. On the radio plug it is located at row E pin 2.

    Exactly what I was thinking.

    Question though for those who have done this. I installed an 05 Escalade Nav into the Trailblazer I used to own. It didn't come with nav so no speed wire going to the radio harness. Until I installed that wire you're suggesting to clip I had issues with the GPS where it wasn't smooth operating. The vehicle position on the map jumped by increments rather than updated. The faster I drove the bigger the jumps in position. I think the GPS needs the vehicle speed reference to update the position reliably like in tunnels or tree covered areas. I spliced into the IPC and it operated smoothly as it should after that. I'm guessing the update rate of the GPS is complimented by the vehicle speed for a smoother position representation. If you rely solely on the GPS antenna then you're at the mercy of your surroundings like your XM radio that cuts out when driving through tunnels or wooded areas.

    The lockout option is a pain but I understand why GM put it there. I contemplated putting in a rocker switch so a passenger could work the GPS while the vehicle is in motion.

    Your correct, the gps for the nav is not always on it uses the speed sensor mainly and updates with the gps ant every few seconds thats why it wont track smoothly without the speed input, thats why a switch is recommended on this mod, turn off the speed wire enter your destination then turn back on

    That's what I am talking about, my Escalade doesn't have navigation there for, why would my harness have the green wire with the white stripe on it when it wouldn't matter for my non-navigation head unit? That's what I am trying to ask, I just want it to work properly and don't want to put some sort of switch to have it work on the go. I can take a picture of he harness I have an gladly e-mail it to anyone that would like to see there is no green wire with a white stripe.

    The ones without nav that have the wire is used for the speed controlled volume
