I have the 510 too and all other kinds of scan tools also.
The 510 is great feature wise. I have bmw, ford and Chrysler unlocks on mine.
As stated it works great.
Its only drawback is its SLOW. I mean 100 MHz pc vs 3.2 or more ghz pc slow.
Go find something to eat while waiting for it to scan the vehicle the first time slow.
Smoke 4 cigs while waiting on it to scan the car slow.
Watch paint dry slow.
Watch plants grow slow.
You can cut the grass completely waiting on it to scan a Chrysler slow.
Bmw's scan a bit faster but not by much.
I can go find my notebook computer plug up a drop cord and drag it to the car. Connect the laptop up to power and cables and plug into the obd port. Boot windows. Run the emulator, boot windows inside the emulator, fire up pa soft, connect to the car and scan codes and read the codes and reset the check engine light if needed in the time it takes the 510 to do a scan.
SLOW.
But it works great if you have the patience for it and its small enough to keep in the car without hassle
