what do you guys think who have the GM navigation system is it worth it?

I do have RAM mount for my iPad that I do use also.

thanks!

 

Works fine and nice not having wires everywhere but updates are expensive...$200 up here in Canada I believe.

 

Some really nice aftermarket units are available for much less money, and more features. If I had it to do over again, I would seriously consider them. (I have 2012 Silverado LTZ with factory nav)

 

Tried ours against my Garmin 1000.
While the Garmin was spot on to turn, the NAV would tell you to turn when you were already in that process.

And the arrow that shows your direction of travel is odd when you are used to the Garmin actually pointing in your direction of travel.
Save you money for better tires or something else.
A free standing unit is much more accurate.
