The disc in my 2007 is way outdated, does anyone know the best way to update the navigation? The dealer wants almost $500 for a new dics. Gotta be a cheaper way. Any suggestions?
Thanks

 

Ebay has them cheaper, just type part number or disk you need or want

 

$500 are you sure? they are $200 from the official site

I got the new 6.0c version off Ebay for $100 it was a very good improvement over the original 3.0 version that was in there. I suggest looking at the upgrade.
