Boot GPS device to Windows CE

I have a GPS navigation unit that operates using Windows CE 5.0. When powering up the device, it goes to the Windows CE start screen, then on to the factory default OEM screen. I want the device to boot to Windows screen by modifying the Registry or other means. I have the unit hooked up on my windows vista home pc and can access files on the device. ## Deliverables I am new to Windows CE and the coder will need to be patient with me. I am customizing the device for my own use and this is the first of several projects on this device. If you need more information to bid, I can furnish that. Thank You.
