It is not possible to update anything in your Jeep wirelessly.
There are 3 different kinds of updates with MyGig radios:
1. Mygig software - This is updated with a CD (you can download the software yourself for free and make your own CD's (current version is 2.302)
2. Gracenotes - This software identifies your songs and new albums (also updated from a DVD and can be downloaded and installed for free (current version for North America is 2064
3. NAVTEQ map software - This software is VIN specific and costs $199 from NAVTEQ. The update is performed via CD like the others and updates POI's and new roads/ subdivisions.
I personally don't think it is neccessary to update the NAVTEQ software often but if you do it every 4 or 5 years should be sufficient. (basically one update during your ownership of the vehicle if you even have it that long)
