Many already know that the processor of 3400 family is different and faster that the 3700 family. The purpose of this topic is to show not only the difference in performance between these families, but especially try to find differences within the families themselves, based in judging the performance of several other gps. The more accurate and reliable for this type of test is to use the set of benchmark available on the Garmin 2012 firmwares in hidden menu Diagnostic Page. I'm not sure that this same benchmark is available in 3700, so I'm using the 3700 with the 3400 firmware to match the conditions.
I hope that with the assessments of benchmarks we can prove or not if there are differences between the models (early, recent or of distinct regions, Asia, USA ..). If such differences may help confirm hardware differences not identifiable, which may have other implications, as to infer that such differences can also be related to the accuracy of the converted 3700 (real hardware difference l and not perceived), among other possibilities (gps malfunctioning...) we'll know after analyzing various benchmarks and for it is desirable the participation of stakeholders...



for those who do not know:
To access diagnostic pages: Press and hold your thumb on the speedometer trip computer page (press speed in the map)
To capture the screen: Setting / Display / Screenshot (the images are in the Screenshot folder of the internal memory of the gps)
