I personlly use AstroGPSLauncher. Just place the folder in the root of your device. This one is configured if you have TT on you storage card (\Storage Card\Program Files\Navigator\TomTom Navigator.exe). Just copy the shortcut within the AstroGPSLauncher folder to the start menu. TomTom is looking for the software port(Comm 5) and not the hardware port(Comm 4). Made a video of how to configure TomTom within TomTom
