Thank you so much for your detailed instructions. Dealerships don't bother trying to fix the issue and simply suggest to change the radio which I did once. But it is now out of warranty and I didn't want to spend the outrageous amount they were asking for.
Thanks to you, I saved thousands of dollars and I am now, able to enjoy an upgraded nav system. I got all files online. Total download time was over 90 min. I did not run into any issues or error messages. Everything went smoothly and unit rebooted on its own within seconds.
Thank you again !
