Ratings and reviews

So plugged it as directed and got it connected paired all good i can see live data....., until I cycle the key try to reconnect it goes to main menu and just sits there loads. I can't see live data. Only way I can get it to reconnect it by uninstalling and reinstalling the app. Really scratching my head here thought it was supposed to make it easier.

Don't waste your money. Bought this as my hand held display broken. Urged it in and wired power. Paired to phone the 1st time. Only data showed throttle and nothing else. Things went down hill from there. Called TCI and they said it may take reloading app A FEW TIMES to get it working. Still not working after 6 reloads.

Overall, it's a good app but one suggestion. The error notification on the live data screen should default to grey (like the gear selection) and turn red if an error is detected.

What's new

Updated libraries and targeted SDK. Should fix issues with some Samsung Galaxy phones.
