I'm curious about your experiences concerning USB connecting times for different Garmin units and / or different PC configurations.

I.e. time from connecting a Garmin unit (not yet powered) to the USB until the respective drive symbols show up on the computer.

Here are two examples for my units when connected to a Win XP (SP3) machine with USB 2.0 port:

Oregon 300: 22 seconds
Nüvi 1490: 76 seconds

No difference with or without SD card in unit.

I will post results for my Mac soon.

Please post your results, too. Thanks very much!
