October 26, 2006I was wondering if anyone has been able to make the navigation inputs work when in motion? On my 04 Denali the navigation inputs won't work unless your going extremely slow or stopped. I know this is a safety issue, but BMW allows you to input info on the fly. You don't have to pull over somewhere and enter the info before moving. I'm getting the touch screen nav in a couple of weeks and was wondering maybe the newer versions let you do this.

October 26, 2006My TNR deck works the same way. It might have to do with the VSS wire, I don't know what would happen if you take it out but that could be where the bottle neck is since it is the module that senses your speed.
October 26, 2006It is the VSS (vehicle speed sensor) that locks out the functionality. If you don't mind pulling your instrument cluster you can trace the wire on the back of the connector. It's been a while since I installed the one on my pickup, but I believe it was pin 4 or something.
Doing this does have a negative effect on tracking. At highway speeds the navigation display can be as much as 1/4 mile off from your actual location. Probably not a big deal but I wanted to make sure you knew about it.
October 26, 2006I installed a TNR in our 2003 H2 and didn't realize that the VSS wire was not hooked up on the relay. The location icon jumped all over the place with about 2 second delays. The factory Delphi TNR or INR Nav Radio's have an annoying incremental tracking bug anyway, the absense of a VSS connection just made it worse.
Yes I could input while driving at any speed but it got so annoying that I hooked up the VSS wire.
Other than disconnecting the VSS wire, there is nothing you can do (to my knowledge)
October 27, 2006Thanks for the info guys. I was hoping there would be an easier way to enable inputing while driving. I'm don't think I will disable the wire. It seems to add another annoyance rather than solving one.
October 31, 2006If only the TNR nav had a hidden override feature like that on the nav in my Lexus ES 350; there is a hidden menu option that lets you override the nav lockout...the downside to this is that it reverts back to lockout every time I turn off and restart the vehicle...but at least the lockout override is there. I've been trying to discover if the TNR has a similar feature (the diagnostic menu layout is very similar to that of the Lexus nav even though the TNR is a Delphi and the Lexus is IIRC a Denso unit).

I found a company that enables you to use your nav screen for movies and nav input while on the go. http://www.coastaletech.com/GMLOCKPICK.htm
The down side is the price and they only make it available for 07 models. I know a person who bought the lock pick and he's very happy. Very easy to install. Other downers - cannot adjust volume of movie while in motion. I wish they made it for the older nav versions like mine. Also customer service is not too good. I called them about lock picks for the older model navs and they had no clue whether they were going to make them or not. The people in their customer service are pretty clueless.
October 31, 2006heck, for all that, just pull over and be safe about it.
