PaulT Posted October 9, 2019 Report Share Posted October 9, 2019 I do not use the car often so i didn't bother me that i had map 1.0008 and firmware 2.009 I wanted to use my usb stick and sd card and noticed that they were not working anymore. i put a usb stick and sd card but the menu shows them grey. Thought i'd just reset it, no luck. Thought i'd update it, no luck. What can i do to resolve my issue Quote Link to post Share on other sites
PaulT Posted October 10, 2019 Author Report Share Posted October 10, 2019 Succeeded in updating to 4.0. Removed the unit completely and reinstalled it. USB still not working, perhaps a broken usb cable. Quote Link to post Share on other sites
