Figures I am heading out on a trip around 3 a.m. eastern standard time and decided to update my maps.. well Murphy Law came into effect. I downloaded the Express from Garmin under Admin try to install the updates and Bam error while trying to update no exact error just an error. tried again still nothing uninstalled then reinstalled nope nothing zilch! I looked to see if I could contact Garmin figures there closed. So here I am needing help with short time to do it in. So if someone out there could help me in anyway that I would be very Grateful! Thanks and Godspeed Jay.
I am sorry for the troubles. The 2015.20 unlock code was generated for the Nuvi around 7:30pm. This code is generated right before Express installs the updated map file to the device. Hopefully, you didn't have any other troubles. Let us know if you have any questions.
