I had Nav activated in my Cherokee this morning at the dealer and had some problems with it after. It loses GPS signal and then tells me I am miles away from where I am. Happened to me 2X's today.
It takes a good 15 minutes when you start up after it has been off a bit to acquire signal. Totally unacceptable. At one point the map had me going west in a town 15+ miles from where I actually was AND I was actually going east! A GPS should take no more than 30 seconds to a minute max to get signal.
I hope now that it has run a bit that this issue will go away. If not it is back to the dealer. When it did have signal it worked well at least. Have any of you experienced this issue? I hope it goes away or there is a flash or upgrade to fix it. If not Chrysler owes me $600.
