Chevy Tahoe Nav/DVD in motion security bypass
 
I have an 08 Tahoe LT i bought new a few yrs ago with the upgraded Nav system and DVD player. Is it possible to override the safety system so i can plug in an address while driving. Also play the DVD player. anyone try this?

Had on one in my '08 H2 and have one now in my 2010 super duty. They do work, however, your GPS location tracking is not engaged while the lockpic is on (I think your on/off switch would be the mute key on steering wheel 4X). Once you've entered your address, turn lockpic off and the GPS should re-locate in a few minutes. Watching DVDs is cool, especially in traffic jams. Safety is obviously a concern if you are someone who cant decide where your eyes should be while vehicle is in motion.

Can also purchase Coastal Etech lockpics here:

I use the PAC product in my 05 f250. Only thing weird it causes is some occasional stalls when it starts up and I have to reboot the thing.

Be careful with the Lock Pick.

GM Bulletin No.: 07-08-44-004A
Date: April 15, 2008
Subject:
Diagnostic Information on Navigation Radio Aftermarket Modules Causing Various LAN Communication Concerns and DTCs, No Crank, Vehicle Stability Lights and Messages, TPM Warning Lights, PRNDL Position Errors Models:
2007-2008 Cadillac Escalade Models
2007-2008 Chevrolet Avalanche, Silverado, Suburban, Tahoe
2007-2008 GMC Sierra, Yukon Models Supercede:
This bulletin is being revised to add the 2008 model year, the Sierra model and clarify/add information (Updated information is shown with asterisks). Please discard Corporate Bulletin Number 07-08-44-004 (Section 08 - Body & Accessories).
Some customers may comment of one or more of the following concerns:
^ Vehicle will not crank. ^ Vehicle cranks but will not start. ^ Vehicle stability enhancement system warning lights and messages. ^ PRNDL gear indicator position errors. ^ Tire Pressure Monitor (TPM) system warning lights. Technicians may find various Local Area Network (LAN) communication Diagnostic Trouble Codes (DTC) and no low speed LAN communications with the Tech 2(R).
These conditions may be caused by the installation of an aftermarket navigation radio module.
It has been brought to our attention that some customers may be installing and using certain aftermarket products that are used in conjunction with the factory navigation radio systems.
*These aftermarket products allow the user to display the video output of the DVD player on the navigation screen while driving the vehicle. Normally the DVD output is only available on the navigation display when the vehicle is placed in PARK. These aftermarket products may include additional features such as an aftermarket camera or a second backup camera. These products may enable other navigation functions to operate while driving that would normally be available only when the vehicle is placed in PARK*.
Dealers have found that these products can cause unusual problems that are difficult to diagnose. These products may be difficult to identify because they are installed behind the navigation unit and are not visible unless the navigation unit is removed.
*Technicians may also find aftermarket ipod interface modules installed on the vehicle. These modules may cause intermittent XM reception or the tab on the navigation screen for XM disappears intermittently*.
If you suspect that the customer has installed aftermarket products of this nature and you suspect that the product may be the cause of the concern, you should ask the customer if any vehicle modifications have been made.
Additionally, if the customers information is not available, you may want to test the navigation and DVD system to see if normally blocked functions are available with the vehicle in DRIVE. Removal of the navigation radio will also allow you to verify if one of these products has been installed.
Warranty Information
Warranty coverage does not extend to problems created by aftermarket devices. Damage to normally covered systems caused by aftermarket products is the responsibility of the customer or the aftermarket installer.

I have a device from NAV-TV on my Tahoe LTZ. I have been using it for 3 years with no problems. The nav system will update while driving with the NAV-TV adapter. I also added FLO TV that allows you to pick up 14 channels of TV. Of course, I never watch it while driving!
