this thing has so much potential, but it is full of bugs to the point of being useless. The UI is incredibly slow; when I start up it announces "stopping voice control;" the speed limit warning doesn't work, and it takes forever to get a sat signal. The only reason i got this over a garmin was because it has the "avoid part of route" function. But because it has so many bugs and takes forever to grab a signal that feature is no use to me.
Got this to replace my ailing wrt54g. It was eating my mbps from about 18 down to 1. Setup is nice and easy. I was able to setup and use the included software (Cisco Connect) using Mac OSX 10.4. That OS is not listed as supported, but I haven't seen any issues yet.
