Well as far as bosch go, I have only used it on bosch courses but it looks pretty good, works very well alongside kts. Some guys say it's the best aftermarket info but others say it's full of holes. I always find its best just to try it out as everyone will have a different opinion. I was just about to switch to it for the next year but autodata have informed me that it's swithcing to the new system, so going to stick it out and see how it goes.

At the end of the day day it's still bosch, it's never going to be a bad, just not perfect.
