gahi, I am using the BU-353 and it has worked out quite well. I have a windows laptop with NG Topo and Delorme Street Atlas. However... I can only have one program at a time using the GPS antenna-- both will programs will run, just one has to go without GPS data. The refresh rate on the BU-353 is significantly slower (guessing a couple seconds versus 1 second) than hooking up the lap top directly to my Garmin handhelds. But I am willing to sacrifice a lower refresh speed to be able to have to deal with just one cable from the computer to the antenna outside as opposed to having one cable from laptop to handheld gps, a second cable from the hand held to a power source, and then a third cable from the handheld to an external antenna.
I also will attest that the BU-353, Garmin II+ and GPSmap 60CSX receive a significantly degraded signal in the vehicle as opposes to outside of the vehicle or attached to an external antenna.
