Unless I'm thinking about the prior Z, I could have sworn in my 8000, there was a option in the settings to tell it where the GPS antenna was installed - forward of vehicle or rearward.

Just poking around the 8200. I don't see such a option.

Actually, as I type this, I'm pretty accurate there was such a option in my 8000, as I was never too crazed about it'a accuracy, as it always seemed a couple feet short.....and remember such options when I was tinkering around.

I have an 8000 and have never seen that option

Mike -

Maybe I'm having a moment and I'm thinking about it in the Z Series.

And or it was in the 8000, but a firmware update removed it ?

I kinda remember when GPS had me all over the place on the map, there was a setting that allowed you to tell the system if the antenna was installed forward or rearward placement.
