Here's another device... this one adds not only GPS, but also OBD-II.
So, it can get wheel speed as well as GPS-velocity.

In fact, it can get all kinds of data off of OBD-II.
The big negative of this system is, once again, the software.
Actually, maybe not... it uses (ick; phtt; blech) a Pocket PC
to record the data. But more, it has the analysis software
built right in. So, you can plot maps, etc., right there.
That would be a nice plus iff we could, later, dowload the
data into Geez software. As it is, the software would be fairly
lame in comparison to Geez.
As a system to complement Geez+Gcube, I am not sure this is better
than the DL90... it costs a bit more. For $800, you still have to
buy the GPS receiver and a number of cables. The DL90 comes with
it all. But it doesn't support OBD-II.
Thoughts?
