Hi all I'm trying to figure out why all of a sudden my N1 can't calculate to a distination like return home for instance it brings up a calculation not possible message. It knows where I am all the time. I've had it for 7 months only mods done are the cheat mod for typing directions with out using the emergency brake and didn't do the speed wire which I don't think these are the cause but would like to figure this out. I'm using the disc's that came with it and been trying to do a master reset but it won't do a full wipe address book and my home stay in.

Thanks!!!
