At the risk of being contentious while I agree the Elite can't hack it easily the new Extreme II should be able to - the missing link is Bluetooth. I have a similar tablet with Bluetooth that connects to a separate GPS receiver (a small box with no display) that I originally bought for my Nokia phone. It will position Google maps correctly, the only issue is that of having the maps available if you are out of range of Wi-Fi. I can overcome this using a Mi-Fi unit if I'm away from home or another fixed HotSpot.
I'm not sure if the Open Street map app allows downloading of map tiles, I did have it on my Elite but stopped using it when the Elite went back.
A typical Bluetooth GPS receiver can be found at
