Astx, was a 2595 USA, normal, without Glonass.
I agree with you, the body of 3xxx are small and slim and the antenna should be lower, the difference may be this, but it seems that the chipsets are different (not sure), which may also explain these variations. For not having doubts, would be necessary to make a comparative test with the 2595 but with the original firmware of 3790. Despite the precision meet our current needs, I wanted to emphasize in the previous post that the 3790/3490 is below of the other models (forgot to mention that also compared with the 1390T and the accuracy of the 3790/3490 was much lower). In short, for me the question of accuracy remains open (at least in terms of curiosity), indicates to be related to the firmare and the fact is that the 3790/3490 in this respect is below the average of other models from Garmin, the rest of it is great, do not intend to use original firmware.
