Question for Fedora users of Garmin nuvi GPS

Hello, Everyone I know that I can just go drive to a computer that has Windows installed on it and get this over with, but I shouldn't have to do that... I have new Garmin nuvi65LM GPS and of course the "GarminExpress" updating program that they force you to use only runs on Windows and Mac. I tried installing the Windows version using Wine, with no luck. I then successfully installed GarminExpress in a virtual machine of Windows 7 that I have installed on Virtual Box. When it tries to detect my device, it says that it can't... If they would just let me/us manually download and install updates, I wouldn't care if I can't use their Windows based application. So, if any of you have succesfully updated any Garmin GPS that forces you to use "GarminExpress", please let me in on your secret. Thank you, Steven P. Ulrick
