5 Alive

Just bought a 2014 silverado that just has the OnStar nav. Is there a software update or any way to get a full navigation system installed? thanks

If you want the nav system like is optional from Chevrolet, there needs to be a lot of changes, starting with replacing the HU.

Just go buy a nice Garmin....I am not impressed with my factory Nav on my 2014 GMC. Inaccurate and the voice for pronouncing street names is terrible. Upgrades to software are $150+. No thanks! I use my truck to tow a big fifth wheel and there's no option for inputting dimensions to keep me out of trouble.
