Won't find my device
I downloaded this app store version thinking that it would find my 3790 Nuvi, but it won't. I rebooted, I tried their communicator plug in, but none of that worked. The old app seems to see my device and download the updates, but they won't install since it then says it can't find the device. My Mac and Safari are fully up to date and I tried it with Chrome. No useful error messages either. I will have to find a PC to update the maps. The device won't mount as a drive like their help pages say either. However, it charges fine from a variety of USB cables that I tried. Those cables work fine for other devices. My TomTom Software works much better for my other GPS unit.Hints For GarminPut some error messages in there so at least people with a clue can do some more work finding out why it might not work.Update you help pages beyond old versions of the OS and browsers. The old updater apps used to work a few months ago.Blame Apple, but, your debugging team should have figured things out and issues an update. I can't be the only Mac user out here.
