This is the Navigation update disk AG for Jeep Chrysler Dodge with RB1 or REC units. I've uploaded this for those who have units with version AE or lower. This installs a firmware update that seems to help the unit read later disks better or in some cases allows them to read them period.

I have version AL uploaded here on PB also.
