Thread: My Nüvi 3490 is less accurate than my 1490...how come? Is it fixable?

Hi everyone...

So far I've had a Nüvi 1490 LMT, and recently purchased a brand new 3490 LMT.

The 3490 is supposed to be a more advanced model, but I've noticed that if I go to the satellite page, its accuracy is a lot worse than my 1490...how can that be??

My 1490 consistently shows 7 to 13 metres of accuracy, whereas the 3490 has 20 to 30 metres (sometimes even 50 to 60 metres!) I've done the "Cold Start" and "Predicted EPH" trick, but it didn't seem to help.
Note: I've always done "apple to apple" comparisons.... (i.e.: always when both units show 5 green signal bars on the top left corner, placed literally side by side.)

Another weird thing I've noticed about the 3490 is that even when I am completely stationery/completely not moving, it *sometimes* shows a (small) amount of speed....between 3 to 5 km/h. My 1490 never does that.......if I'm stationery, then it always shows 0 km/h.

Are there any ways I can tweak the 3490 so it will perform better?

P.S: I have the latest firmware for the 3490, which is 7.90.
