Factory Navigation Question

Hello to all,


I am looking at upgrading the maps on my 2008. I'm pretty sure I need to update the firmware first and am wondering if anyone has the update.gcd file I need to do that?

My other question is that I have a Garmin in my truck with lifetime map updates. Do you think that I could use the same maps?

It is crazy that you buy a $130 Garmin and get lifetime maps yet the $3000 option on a vehicle doesn't.

Take a look at this thread on another forum and it will have all your answers. This is what I did and have 2019.2 loaded on it. Make sure to read as much of that thread about the limitations of doing it. I have my card loaded with the lower 48 only.
