Hello, thinking of purchasing the Rider 550, looked at the new Garmin zūmo 396 LMT-S but it has a slower processor (CPU) then the Rider 550. How fast the processor is has been a major factor in my decision making. Also I like the Tom Tom Drive website route planner functionality. Its alot better then the old obsolete Basecamp standalone software offered by Garmin. The display of the Rider 550 not 100% yet. My only concern at this point is visibility in sunny weather. I would like to know how easy is it to see and read what's on the screen when the sun is shining directly on the screen or in sunny weather in general. Your feedback would be much appreciated.
