Yes I did the update a few times and it worked without problems.
I started on the InControl website
Selected Download Map Updates under the most left "Touch Pro and Touch Pro Duo" heading.
That gets me to the jaguar.here.com site and I have to sign in again.
On the bottom right I select Go to Maps & Services
For me I select the North American Maps + Services (3 y subscription)
Version Number: 08.030.0100.0153
Click "Get Latest Version"
Click Download Map
It opens a box asking me to open the Map Downloader tool
The Download Tool opens and I plug in a USB stick with at least 10Gb of space (I am using a SanDisk Ultra USB 3.0 32Gb stick)
After the download is done I just take the USB stick to the car, turn on the car and wait for the navigation system to load.
Then plug it into one of the two USB ports under the central arm rest. The car recognizes the map update and on the main screen it asks me to install and after about 10 minutes the update is done.
A few things that may be going wrong that I can think of:
- You didn't select the Touch Pro Duo version?
- You are using a USB stick that is somehow not being recognized (cheap generic?)
