9500ix GPS Speed Accuracy

[Obsidian]

Most car speedo's are off, especially the faster you go. My S2K for example is fast about 2 MPH at 80 compared to the 9500ix. Tire wear will also impact most cars speedos. I would think some cars must have GPS speedo's built in by now ... not sure though.

I trust the 9500ix, although it does have an annoying lag.

The lag on mine isn't that bad? Maybe I just drive a slow car.

LOL. I don't know. Mine takes about a one half to one second to catch up or slow down. Even coming to a red light or something it will show 3-4 mph for about a half second after I stop.

Oh yeah, mines about that lagging. No big deal to me, I guess. So are you running Speed Display and Spec Mode?

Yeah, maybe it's not too bad. The satellites are in outer freakin' space after all.

I run speed display (but not speed alerts) and spec mode. I sometimes switch to expert since every CHP is running 34.7 anyway.

Every one of my vehicles is off per my 9500i speed display. My freakin truck is off by 10 mph at 65! ( I am actually only going 55) Once you use the speed display, it's hard to live without.

Same here. Speed alert makes it take longer to display the frequency.
