Customers tell how they fix their MyGig Navigation / Music systems

I was seeing the Can't Unlock Maps  message for over a year and could never find a solution on the jeep and
dodge forums or with dealers.  Then I finally found a link to your site on a recent forum post.  An easy fix.

I received the nav board,  installed it in about an hour and works like a charm.  I was unsure if I should order the board but the instructions and photos showed me it was an easy replacement.   Very happy I found your site.
