After having sent a route to my Garmin, i have to disconnect and reconnect the USB cable.
Otherwise, if trying to send annother route to the garmin, SD reports "Receive Thread Exception".
After dis/reconnecting the next upload works fine.
Not a big deal, but a bit uncomfortable.

Garmin GPSMAP 495 OS V2.70
SD V3.0.7.0
OS Win7 32Bit

Apparently it's a problem with the garmin drivers according to SD.
I also get "thread exception" on XP....It completely locks up and crashes on my win 7!
I have not been able to find a fix.

Using Garmins MapSource V6.16.3. there are no problems sending many routes consecutively without USB interruption (from gpx files).
EasyGPS has the same problem as SD.
Obviously the error occurs after having sent a route when SD receives initial data from the Garmin.
The issue is clearly reproducable.
