I have GpsMap 62s andy thinking about a upgrade. (ues the 62s since 2012)\nI have seen some videos on YT, but one thing is not mentind there. \n\nIs the 64s musch faster? When I'm moving/scrolling on the 62 it is often slow in reaction. IDoes the 64 respond faster?\n\nAnd another thing. When i conect my handheld to PC and use basecamp. There is some "slowness" there also. Take sometimes long time to fully load map, and when i zoom in, the screen is grey for many seconds before map is loaded. \n\nIs it:\n1. Since the map is on the device and run through a cable\n2. My PC thats not good enough\nMust be the first, my PC is 2 years old... and not a cheap crap.
