Now I'm just not following you as to what stage you are up to. In post #3 you said 'It loads fine but the computer never sees the garmin files'. By 'It' i assume you mean the cure3 firmware and if that's loaded the nuvi should normally immediately enter Mass Storage Mode if a faulty file was preventing it booting past the logo screen.
What do you mean by 'The problem is I need to keep my finger in the top left corner of the garmin while doing this and after a short time you here [sic] the disconnect.'? Do you mean you haven't been able to get into preboot mode to even load the cure? Or have you flashed the cure and you are trying to access MSM by holding the top LH corner? That's only to get into pre-boot, and in preboot if you don't start flashing within 30 seconds it will go to the white calibration screen if it's not connected to the PC, or if connected it will give the 'du du du' disconnect sound and to go MSM if it's able to.
Please post a 'blow by blow' full explanation of what you've done so far so we can understand where you are stuck exactly.

I have used cure 3 to load the normal firmware, then I select the cure and install the .rgn file. I do this by holding my finger in the top right corner turning on the gps and as soon as the gamin logo comes up I connect to the usb I then hear the connect tone and start the process of loading the file. This is the only time that I can use the cure. It will install and says complete when done. Then I am back to the same problem meaning all I can do is turn the gps on, the logo comes up and just hangs there. If I put my finger in the top left corner turn the unit on then connect to usb I hear the connect tone but cannot see anything in "my computer screen"while looking for the garmin file the device will disconnect in 30sec or so. The screen of the gps never changes from the garmin logo, so I can only assume that I get into pre-boot. The fact that I can load the cure or .rgn it must be, but that's all I can do. The only thing that I see on the garmin screen is a quick flash just as it starts loading the file. I hope that this helps you understand what I have done.
