I have been using a Sat Nav app called 'Route 66' on an HTC phone, and was very impressed with the features - so I installed it on my 7cG2. It's still very impressive, but there is a feature called 'Follow Me' that works on the HTC, but not on the 7cG2.
See Here for how it works
This is because it needs a rear mounted camera, which the HTC has, but the 7cG2 doesn't.
I think this is such a useful feature for navigation, that it would be worth trying to add a rear camera - but before I stumble into the void, has anyone done this already?
I would consider:
1. Stripping the tablet to see if the front-facing camera board could be rotated to look through a hole drilled in the back, or extended outside the casing.
2. Making some kind of periscope with a couple of mirrors so the front-facing camera could see the right way (which would obviously need the image to be flipped).
3. Making it work with an external USB web cam, running via the OTG connector.
That "follow me" feature in Route 66 seems really fun and that's a cool project you have here.
Option 1 is probably hard has the tablet cases are usually really stuffed and there isn't much space available to change components place, you'd have to unsolder the camera component anyway, not always easy if it's CMS mounted.
Software option 3 is easier in theory. It seems there is some hardware support for USB cams in Android thru Linux Video Class (UVC), but it's apparently targeting Android 4 ICS and only for special camera models. I don't know if the 7c G2 being on Android 2.3 Gingerbread has access to that, another question is not having the kernel sources won't help if some devs or modifications are required
Here is a video of an USB cam on a Tegra 2 tablet running Android 4

Thanks Admin, I think the external webcam might be the way to go, as the onboard front-facing camera is a poor resolution anyway. I'm just not sure how Route 66 will choose the right camera if there are 2?
That 'Follow Me' feature has got to be worth it though - the 7cG2 is perfect for sat nav!
the camera on the 7c g2 and g3 ar connected thru some type of pins which thei fit in some slots, the camera from the 7c g3 (front camera) is a little better compared to the g2.
there is enough space on the back of the g2 so you can drill some holes, but i don`t advise you to do that.
the 7c g3, has a rear camera, but needs some improvement.
have a look on this
but again, you need android 3.1
