Thanks for the information. It looks like I will order one and try it out.
Another question.
In a rally you are given a odometer check stage. That means to make it fair for everyone, the exact mileage for the first stage is given to you so you can correct your instruments to match the rally masters.
So is there a way, for example, if I find the SGII trip millage is different that the rally masters millage, that I could correct it in the SGII? If so that would be great, otherwise I would just manually correct for it.
