As how to reformat/reinstall on a TomTom 340 XL if you can get your maps off it, if you can't get the maps then you would have to use your latest map guarantee...
Very similar to the technique you used...

Thank you so much for helping me out!!
I almost gave up when I tried several ways but still got "no maps found" on the screen. Your method was my last resort and I made it!
I registered in order to show my appreciation
