For MAC's only!
Make sure to rename the disk to whatever the update is!!
when I downloaded the files whpony96 provided.. one of them was missing the version number. it needs to be like this for the System update =
and this for the Gracenote update=
so again to recap
To update the navigation operating system you will need to download this file
go to software updates - gracenotes update and\or RER 2.403 Update
1- Unzip it
2- you will see a folder. make sure that the folder title is RER_2.403 and that there are 2 files and 1 folder inside that "RER_2.403" folder.
3- Insert a CD
4- (Mac users only!) right click the RER_2.403 folder
5- you will see Burn "RER_2.403" to a disk. click it
6- double check the CD name. again make sure it's RER_2.403 or it will not run on your nav.
7- select the slowest speed to burn.
8- wait for it to finish.
9- start your Jeep and wait for the Mygig to load.
10- insert CD
11- wait for the screen to load. then select update.
12- DO NOT TOUCH ANYTHING! DO NOT TURN OFF YOUR JEEP! let it install and then once it's done it will restart.
13- Mygig will bring you back to that same screen you were prompt in step 11. at that point you can eject the CD and shut off your Jeep
same case with the Gracenotes
if you are updating your maps (you have to pay $150 for this)
it will take an hour and also you don't have to keep the Jeep on. you can let it download while on ignition.
