Navigation

rick08 · June 5, 2016

I have a '15 Sierra without navigation. I am looking at the factory io5 to io6 nav upgrade.Just interested to see if anyone has done this upgrade and what their thoughts were as far as the performance etc of these nav systems.

I have read all the threads on the MVI navs, just not sure if i need a unlocked setup.

Thanks in advance

Maybe a try

I did the MVI/GM navigation upgrade. The installation was very easy and everything works great. I don't understand all of the complaints about the speed of the unit or it's capabilities. It does everything that my Garmin does relative to navigation and it is just as quick when preparing routes or rerouting. A pro for the GM Navigation is that I can look up a route on my GM app and send it to my truck. On the other hand, my Garmin map updates are free, whereas the GM maps are around $150. I like the unit but keep my Garmin in the cab as a reserve. I didn't see the need to unlock my unit. I stay focused on maneuvering traffic when I'm behind the wheel.

Also, be prepared to deal with OnStar and Sirius if you do the upgrade. They have to adjust their records to show that you have navigation before you can us the GM app to send your route to the truck or use Sirius traffic and weather. All of that is pretty well documented on this site.

I'll save the $1,000+ price tag and use my phone for GPS.

lol yup. Google Maps is just as good if not better than any stand alone GPS or built in GPS of a vehicle. Plus it's all free. I also bought a holder for it that suctions to the windshield if it's a longer trip. I know the screen is much bigger than a smartphone's which might be better for someone with bad eyes, but I have no problem with it. I thought about upgrading mine for the GPS since you can also get weather, but of course I have 4 or 5 weather apps on my phone as well so no real need. The only real plus for built in GPS on these trucks for me is that it tells you the speed limit in case you're not familiar with it or can't remember.
