Anyone have issues with the GPS speed limit warning announcement?

I call her "Betty"...The GPS system"voice" that says "The speed limit is 65 miles per hour."
Well, I don't dislike using it. It has slowed me down several times when I haven't been paying attention to the posted speed limit like I should be. I seldom speed. I can't afford the tickets and the insurance bump, so I usually only fudge the limit by a couple mph or so.
The issue is for me, I have set the warning announcement to occur at 8 mph over. Very often, the announcement happens at 5 over. On the freeway, 5 over is safe and outside the "ticket threshold". So why is this thing announcing at 5 mph over, when I have verified that I have it set at 8 mph over?

I haven't had the factory nav yet but on my aftermarket nav in my current truck, the setting goes by a percentage of the speed above the limit instead of a particular speed above the limit.

Have you tried setting it higher and see what it does?

I never intentionally speed.

But for that oops moment, we have ours set for 11 over.

The speed warning is based off of the GPS speed, which is different than the speedometer. I'm guessing the GPS just incorrectly estimates the speed based off of the satellite position sometimes. I have 35's on my truck, so the GPS speed and speedometer reading are always different.

Betty is based on the GPS speed that it is sensing, not the speedometer speed. You speedometer may be off by a few MPH( possibly due to tire size difference from factory size), Dealer said Chrysler is only required to be within a 10% window of accuracy on the speedometer from the factory.

I had this issue when I first lifted my truck. Tires were larger than stock, so rotating less rpm's that calibrated for, speedometer was showing slower than my GPS speed and what I was actually going.

Had dealer attempt to calibrate for tire size, but they set the tires too big and I was then getting more RPM's than it was calibrated for. Speedometer was reading faster than GPS and what I was actually going.

Bought the Hypertech and set my calibration for the correct size now my Speedo, GPS speed and "Betty" are all in Harmony. My 35" Toyo MT's are actually around 34.1 inches, the Hypertech lets you adjust in .25" increments.

Hope that makes sense.

Generally speaking, GPS derived vehicle speed is more accurate and reliable than the truck's speedometer.

How accurate is a GPS-based speedometer? | GPS Systems

Just make note of the offset in speed and put in a number that will give the warning at the speed you want.

And the powers that be on here will spank you for posting the naughty word here, even with asterisks taking the place of some letters...
