Guys,
I have about 3500 miles on my 2011 LTD FWD V6 HLder with the factory JBL/Nav package. I haven't used the Nav that much and have the same complaints that others have about not being able to use some of the functions when in motion/not in park but I stumbled upon another issue that there may be a solution for - hoping someone out there has an answer.
I was on the interstate on a trip and it was showing an upcoming exit in 19 miles or so as part of the route. So, I take the exit it was calling out and just as soon as I take the exit and get off the interstate, it told me to turn around and get right back on the interstate!

I hadn't gone 500 yards before it told me this. Very frustrating because the exit was very congested with traffic and it cost me about 10 minutes navigating back onto the interstate. I use the nav to save time and effort but on this trip it cost me time/effort.
Has anyone else seen this? Solution (other than buying another Nav/GPS)?
If no obvious solution and this is just indicative of the crappy nav system, I may just wind up buying a Garmin and use it for primary nav and maybe use the built-in for POI's and map only - taking advantage of that big screen. I see that Amazon has a cigarette lighter type of pole mount for the Garmin that I could use in the right hand 12V socket which would put the Garmin just below the factory nav on the right side.
Any help or suggestions is appreciated.
