I Have a Tom Tom ONE V3 and have tried a couple of Navcores and Maps and everything seems to work fine except when i plan a route via postcode or city name it freezes saying writing route instructions and then reboots. I Think this may be a Ram Issue as there is only 2mb unused if so would using an older Nevcore help.? Has any body come across this problem before.?

Check my 9.485 located in the Navcore section.
The MB version schould give you around 9mb of free Ram for fluent navigation.

Thanks for the links Downunder the Memory Boost Version worked great . It gave me around 6mb of free ram. The Navecore also loads faster.

Good that you got it working now, thanks for the update.
