    I tried it a few days ago at Athens Circuit (Megara) in Greece and I was very dissapointed as it didn't work at all. Afterthat I sticked with my previous gps lap timer that works perfect for my needs.

    With an external GPS and Bluetooth OBD reader, coupled with the Devices and Analysis packages, the amount of telemetry you can log is invaluable. I put it all together with RaceRender3.

    Had AZ motorsports park already included . Placed in dash of 944 spec car. Worked right out of the gate. Mapping occasionally shows me just off track but the ability to see speeds at corners and braking gradients helped me with troublesome corners.
