Hi I've been tiring to find a file for my TomTom XL Canada 310 N14644 (same as link: TomTom XL - OpenTom). I even tired getting help from their technical support and no luck. My TomTom has the case of the red cross in start-up. The file that I've been tiring to find is called "patchfilter.dat". I believe this is my golden key to repairing my gps. If i had a friend with a similar GPS I would get it from him/her, but dont. The reason for this is because every time I connect to TomTomHome2, it keeps coming up with the same error message which is "Error Reading file: E:\USA_and_Canada\PatchFilter.dat". I was hoping if by any chance someone with the same gps could email me the file or help me fix this problem? Please help me and thank you for your time.
