Navman N20 Unlock and TT install

Hello, I have been reading up on the unlocking of a Navman N20.(Have one but havn't touched it yet) I understand the unlock process but am finding it difficult to get a guide to getting tomtom on to it. If I could ask a couple of questions any answers would be much appreciated before I embark on the unlock

1. After the unlock what files,if any are left in the root of the device
2. Do you then intsall a TT navcore and map and activate, if so, where
3. If it all goes t*ts up how easy is it to replace the original back up files

I am sure I will need more help but this will give me a good start
Cheers

Scroll down until you see Navman_N20_Unlock in the download section

It works by modifying some files on the device, nothing is deleted, Your device will boot to a desktop instead of the default app.

It's reversible by running the unlock tool again.

It's advised to run new applications from a SD card.

It's pretty much the same procedure for all Mio/Navmans, Follow this guide but use the Navman_N20_Unlock instead of the Mio_Moov.zip unlock.

Thanks for the rapid reply.Excellent guide, Looking forward to starting this now. When runing from an SD card do you copy everything from the device and the new files to the card or just the map,navigator,zip and fastactivate . and just curious but whats the difference between a navcore and Tomtom 7.450 for WinCE . Finally will a USA map run on this unit with this set up.
