Has anyone installed a DVD/Nav Lockpick in a '09 Tahoe/Burb?

I am trying to find out if the Nav quits tracking when the DVD Lockpick is activated.

What position did you have to put the number 1 dip switch in to work? Up or down?

 

I have a 07 tahoe with factory nav and the lockpick. Im sure it works the same way but yes, the navigation will stop tracking you as if you were parked if the lockpick is activatied. When you deactivate it, it will start to track your correct position within 30 seconds if your moving.

What i do is that if im going to be on the interstate or some other hwy for a while, i will activate it and when i get close to needing the navigation, i will deactivate the lockpick a few miles before i start having to change roads. It will re-calculate your route automatically.

As far as what dip switch to have it in, i will have to take a look for you.
