Just my opinion. Don't buy a factory installed GPS. My unit in my 2006 Dodge is crap and updates cost $230. If you keep a vehicle a few years the technology has passed you buy. New GPS units with life time updates run in the area of $200, the GPS price on a new vehicle is $1000 plus and you are stuck with it as long as you have the vehicle. This is what I have learned, education is expensive.
