Hi dhn
Thanks for that and for replying to my post.
In fact, that is what I have on my Start and it was working just fine until firmware 9.053 came along, whereupon it wouldn't load correctly and, in fact it took me to (I think) the "advanced" options menu when I tapped "Done" it took me to the ordinary options/preferences menu and when I tapped "Done" on that it took me back to the advanced menu again. In other words, I couldn't use the device at all, because I never got to a menu with a "Plan Route" option or anything else!
Took out the sdkregistry folder and I got the ordinary "Start" (much reduced) menus and that worked fine.
Of course, the reason I installed a custom menu was to get the more advanced features that are not on the standard "Start" menus and I faced losing that functionality. I wonder if TT have got wise to this and disabled the sdk functionality in the latest firmware?
If anyone knows more about this, I'd be interested.
