After you have installed the driver and attached the GPS to your computer or laptop, Windows Vista will ask you for the driver cd-rom. Click the button you don't have the driver disc and want to see other options. Then select the option to manually search for the driver. Then click 'Browse' and browse to your username (in the image below it is 'tester'). Below that you should see a folder with a name in the form of '{a1b2c3d4-...' and so on. Select this folder and press 'ok', Windows Vista should now be able to install the driver and afterwards you should be able to use the GPS.
A new driver for Windows Vista should be available in june 2007.
