Thanks for the reply, its basically what i have found. some do some don't. don't do the upgrade do the upgrade. I love the tekin gear but its a pain to lug a laptop around just to change the settings and use the data logging, which is a great feature but no good when your at home. The biggest problem is that im the only one who runs tekin at the local track so trying to find out what Android device works is the main thing.
