My Titan has a OEM GPS that runs by a SD card. They want $99 for an upgrade. My question is I can get this upgrade from Garmin on the SD card for $39.00. Will their maps/format work in my system?
I had the same thought for my 2010. I found what looks like a dvd player under the passenger seat and it says Garmin on it. I was thinking that I could probably get a new city navigator disk and update it that way.......???
