I've downloaded Europe_Truck_3649 and Navcore 8.398 and followed all the guides/faq/help threads on here to try and reinstall truck maps on to my sat nav.
The sat nav is a Tomtom One XL and I'm using a 4gb SDHC card for the truck maps as the internal memory isn't big enough. Is it the SDHC card causing my problem?? rather than using a standard sd card?
I've unzipped and copied the maps and navcore files to the card, copied fastactivate.exe on to the card and done each button in turn. Sat nav will power up, show the map splash screen picture but won't "fire up" so I can use/view the maps it just gives me a black screen. However the first time I turned it on it did load up ok and let me browse the menus for about 15 seconds before crashing and now it just gives me a black screen everytime.
As far as I can tell and understand I've followed all the steps and guides on here but I'm stuck now, it's probably just a small thing that has gone wrong but I need a bit of help please.
The error of my ways was quite simple and erm embarrasing - me being me decided to play with the menus and try night colours without realising that by default night brightness is set to 0% so even though it looked off it was actually on. A few resets and some brain thought later, i've altered the brightness and it appears to be working spot on
Thank you GPS underground for the help and guides (ps. maybe add about the night colours to save anyone else suffering)
