Garmin released their 2010 map update yesterday. After an initial hiccup, the update is now working properly and you can safely go ahead and install it.
Here's a step-by-step guide on how to install the new maps onto your Garmin GPS.
Current Garmin NuMaps subscribers, and anyone who purchased a Garmin unit within the past 30 days is entitled to update for free. Everyone else can purchase the update for $70. Personally I find the NuMaps subscription a better bargain, since it only costs $119 (for North America) and gets you up to 4 map updates per year for the life of the GPS.
Figure 1: Welcome to myGarmin
Launch a web browser, go to Garmin.com and click on myGarmin. Login using your username and password, or register for a new account if you've never setup an account.
Figure 2: myGarmin Homepage
If you haven't already registered your nuvi GPS on Garmin's website, you'll need to do so before proceeding. Click Register if you need to register the nuvi.
If you've already registered your device, you'll see an alert displayed letting you know that new maps are available for that unit. For example, figure 2 above shows an update is available for my registered Garmin nuvi 765T. Click Get Now to continue.
Figure 3: MyMaps
If for any reason you don't see a notification that updated maps area available for your unit, click on the myMaps tab, then click Map Downloads to see a list of available map updates.
Figure 4: Map Downloads
Click on the PC or Mac download link, depending which type of computer you're using.
Figure 5: Garmin Communicator Plug-In
If you haven't previously installed the Garmin Communicator Plug-In, you'll be prompted to do so. Click Run to install the plug-in (this lets your browser communicate with a Garmin GPS connected via USB to your computer).

If you see the error shown above, connect your Garmin GPS to your computer using a USB cable, and click Try Again.

Figure 8: Launch Download Manager
Once the Communicator Plug-In has detected your GPS, and is ready to begin downloading the map update, click Launch Download Manager.
Figure 9: Install Download Manager
Your browser will prompt you to install the Download Manager, or scroll down and click the link to manually download the update without using the download manager.
Using the Download Manager allows you to resume an interrupted download instead of having to download the entire file again should the download process get interrupted.
Figure 10: Save As
Save the map update file to a location that will be easy to find later, such as the desktop, or a folder on the desktop. In this example, I've chosen to download the file to a folder on my desktop called "Garmin Map Update".
Figure 11: Downloading
The 2010 Map Update is just under 2GB in size, so downloading the file can take a while, depending on your Internet speed.
Figure 12: Download Complete
Once the Map Update file has finished downloading, click Launch to begin installing the update.
IMPORTANT: There will be a considerable delay after clicking Launch as the 2GB file needs to expand and load, so don't be alarmed if nothing happens right away. It is normal for there to be 2-3 minute delay before you see anything open.
Figure 13: Manually Launching the Update
If you clicked Exit instead of Launch in the previous step, you can locate the downloaded file and double-click it to launch it.
