The catch is that we have a T1N Sprinter which is ten years beyond last production, and as I understand it, we still have to resort to the internet to look up the codes. They can't be downloaded into the app. I don't know if this is also true of the NCV3. Husband will likely chime in after he gets off work.
So far this tool works pretty well. It's one of the first Bluetooth OBD dongles for the iPhone so it isn't supported by every app out there which was a bit of a disappointment. But it at least keeps the wifi free to google search codes.
Most apps let you custom configure lots of gauges to watch speed, RPMs, boost levels, mass air flow, calculated HP, fuel consumption, etc. But as IB noted it doesn't have a code database. I don't hold out any hope that an app developer will ever incorporate the thousands of possible codes into their software for a vehicle that isn't in production and didn't sell in huge numbers.
The scanner was relatively inexpensive (~$30) but more than the $10 scanners for android devices. It will only read sensor outputs and read and clear codes. It won't Let you command any diagnostics or reset or reprogram any parameters so it is much more limited than the old DAN scanner I'm hoping to one day find.
In the meantime, something like the iCarsoft MBII i980 may be a decent compromise at the ~$200 price point.
