Has anyone purchased an Terrain with a navi-package?
What do you guys like about the response an accuracy of the navi?
Do you guys find its slugish, maybe needs an update? or should i just go for an after market deck with navi or just, a window mount GPS unit.

I find the navi system too verbose and intrusive, especially when I'm listening to news. I lose alot of what is said so I use OnStar most of the time.

I rarely use my NAV..most places I know where I'm going..But when I do, you it gets the job done..
If the 'turn by turn' instruction voice volume is too high, you can decrease it or disable it all together.

I was not impressed with the OnStar navigation in the free trial period on our 2014 Trax. Charge me $5 / month and I would keep it active. I just assumed by 2017 the on board navigation would be great ? Well now I hear it is a Tom Tom system ? Crap, hoping to see a Garmin system with free map and traffic updates in there. Looks like I may be holding on to the Garmin GPS then, how dumb is that Tom Tom still paying for map updates. Come-on GM for using that system in their vehicles, good way to force some to payand keep OnStar I guess ?.
