The V7 1000 is a great, low cost ($300 CAN), and portable GPS. Out of the box, the major features include a MyGuide navigation system, an MP3 Player and a Movie Player (supports DivX).
There are, however, a few quirks with the device. For example: the Time Zone settings do not seem to stick and the "M" button is not very useful. It was searching for a solution to these issues that lead me into my V7 hacking adventure.
Warning: Modifying your V7 1000 in the manner described within this instructable may void your warranty and could permanently damage your device.

Accessing Windows Explorer
Fixing the M button "bug"
Speeding up "Fly Over" mode
Accessing the Operating System
