Short description: Desktop application for transfer GPX, TCX, ITN files to Garmin and TomTom Navigation devices.

Full describe
Some GPS navigators from Garmin and TomTom can connect to computer via USB. Application must put in GPS file (GPX, TCX, ITN) to some folder in a device.
For Garmin it is can be folders: “GPX” or “NewFiles”.
For TomTom it can be “ITN” folder.
So need scan USB devices, check in VENDOR_ID and detect Garmin/TomTom device. Detect folder (GPX, NewFiles, ITN). User can select file and transfer (copy) into device.
If user use new TomTom device but not press "Import routes" then application must ask e.g. "Please press 'Import routes' button in you TomTom Rider 400 device".
Application must have association with files: GPX, TCX, ITN. So user can click on such file and open application (or select in context menu “Open with”).
Application must have help window with howto instructions.


Optionally
If application can not detect device or no have needed folder for transfer need send log to Tourstart (ask in user). Log must consist of: VENDOR_ID, MODEL_ID/PRODUCT_ID, folder structure (first level). It is need for improve application for the future.
