TomTom Rider uses the USB Media Transfer Profile (MTP) for transferring routes. On a Mac you need to install a program that supports USB MTP, such as Android™ File Transfer .
Once the program is installed, connect your Rider 40/400 to your Mac and select Import routes . This switches the device to MTP mode. Route files such as GPX and ITN can then be copied to the internal memory of your device or a memory card using the MTP program.
For Windows Vista, 7, 8 and 10 there is no need to install additional software in order to transfer routes. When your device is connected to the computer, you can find it listed as a removable drive in Computer . You can then manually copy routes to the device.
