Maybe you didn't activate your trial?
You cannot use the trial prodct without activating.
See this MS FAQ:
What is a trial version?
A Trial version allows you to evaluate the 2007 Office release for a limited amount of time, typically 60 days. To use the Trial version, you must activate the software the first time you run it. Otherwise, the Trial version runs in Reduced Functionality mode. In Reduced Functionality mode, your software behaves similarly to a viewer. You cannot save modifications to documents or create any new documents, and additional functionality might be reduced. No existing files or documents are harmed in Reduced Functionality mode. Full functionality returns when you activate the software.
You connect the 2720 to your pc with the supplied usb cable. Power up the 2720 with the ac supply cable. Then run the garmin webupdater. It will do the update.
You must have previously installed the webupdater and the usb drivers. If you use the garmin mapsource software and can connect to the 2720, to transfer waypoints, tracks, etc., then the usb drivers are already installed.
You can download the webupdater at this site: http://www8.garmin.com/products/webupdater/howtoinstall.jsp
Unfortunately, Fixya is not associated with Garmin. We can only answer device questions and can't speak for the company.
Unfortunately, the unit cannot be upgraded. Garmin provides both in and out of warranty repair service if the unit is having a problem. The 2720 sells for $49 on Amazon, so it probably is not worth your while to have fixed.
The 2720 is known to have issues unfortunately, it is pretty lowly rated on Amazon.
When updating the maps, you need to be registered with Garmin. All the numbers came with the unit. If you turn over your Garmin 2720, there will be a number flanked by "*". That is your unit ID. When you register, you must provide that ID. From the site, you can update your maps and you shouldn't need the 25digit key. It's programmed into your unit.
Do you use the plug in adapter with the speaker in the plug?
Check it, there is a small volume wheel on it, probably sent it to zero whilst unplugging or plugging it....also check if the power plug is fully seated in the GPS
Mine just started doing the same thing. I took apart the speaker power cord, but don't see anything wrong with it. I thought I saw the unit turn off/on one time when I moved the cigarette plug back and forth, but as I said the wires are fine. I have the power cord apart right now and have 12 volts hooked up to the wires directly and the unit has been sitting here for 30 minutes without resetting.
