Garmin International Support at Garmin tried to rip me off for $49...
After my dezl 580 failed to update the new maps twice with Garmin Express, I contacted support. After a short "chat" I gave them my phone number for a "tech" to contact me to assist with the download. This also failed and the "tech" informed me it was because "MY" drivers were "corrupted" and he needed $49 to fix this problem. Being a past veteran of "techie" rip off schemes I of course said NO.
I tried updating the software on the support site but for "some reason" I couldn't get it to download. Finally I went through the menu on the 580 and saw it was WI FI enabled and would automaticlly update software and maps when connected directly to an internet connection. It took 20 minutes and NO $$$ to update the software and new maps, sooooo.....Beware of Garmin support when they can "fix" your device for a "mere pittance.........
