Title: Serial port is slow!
Review: I suppose I shouldn't rate this item so low because after all, I should've known that serial ports are just plain slow. But when I hooked this up to my Garmin 60CS GPS with the broken USB port, it told me that it would take 3 hours to upload a map set. This is not good enough when I was used to being able to do it in a few minutes via the USB port. Seems crazy too because the serial port is supposed to support up to 115 baud, but I could only get mine to do 9. Not sure what is wrong, but it didn't work for me so far. I think I just need a new GPS with a working USB port.
