OK, this is my first post and I thought I'd share with everyone a file I have put together to run games, apps, and other stuff on my VRVD640G (which I LOVE) so I hope this is allowed...
Just take the following download and extract it to an SD card (minimum 64meg) put the SD card in the slot on the backside of your faceplate and on your main screen click settings and update.

PLEASE NOTE:
This is NOT an update.
It's COMPLETELY SAFE.
Everything just runs off the SD card.
NOTHING on your stereo is modified.
There are a few quirks though:
The main VR3 menu cannot be closed without the "four corner" trick, so my custom menu is set to always be on top. So what this means is that after the custom menu loads up, select your game/app with a single click then close the custom menu (button in bottom right corner) the custom menu will then slide down revealing your game/app! And finally closing your game/app will take you back to the VR3 main menu. Got that?
Also some of the games are not made for landscape mode but will still play although they maybe small/cutoff
And one last note: since the stereo runs Windows CE anything you may change/regedit/etc. will reset back when you turn the stereo off, like wise anything saved like on the desktop for example will disappear. So really and truely you can't hurt anything! 
Anywho ENJOY!
If you have any problems/questions just PM me!
