No problems with software

Installed WebUpdater on my iMac with OS 10.8.2. Plugged in my eTrex Legend CX and run the app. Updated unit from 3.1 to 3.40 version in just a few minutes. In my case its a 5 star since it worked fine. I have a Nuvi 1450T Ill try later and report if there are any issues on that unit.
