2008 Jeep Wrangler MyGig Navigation System Update

[goriding]

Does any one have, and use the navigation data base in the Jeep MyGig system? Have you updated the database to a newer version?

My navigation data base version is M 206 0705, which is obviously quite out of date and is missing many newer roads. I would like to update the navigation database for use in the UAE, but I am having trouble finding a source to buy the data base.

Where can I find a new database to install?

What about off road use? Will this database provide any useful information when off road? I suspect the answer is no, but I would like to have some feedback from someone that has tried it off road.

Thanks, and Happy New a Year!
