With many units now offering free lifetime updates, it is generally not worth it to buy updates.Spend a few more dollars every few years and you can buy a new unit with more features.
For years, Google Maps didn't support speed limits at all, a massively helpful feature on any navigation software.(Also, USB2.0 has essentially been a standard for the last several - maybe 5 - years). The problem here appeared to be not that the map files were too large, but rather that the "Home" software wasn't able to copy the files across successfully. I wouldn't have minded a bit of extra work to sort out downloading the maps, but it's really quite bad for their customer service to have the software fail, AND clear the maps completely, AND not be able to return the unit to factory install, AND have it take 5 hours to install the maps in the first place. After all this hopefully I have the GPS working again, and more importantly, hopefully the fancy new map update was worth the hassle!It's pretty nuts that it's USB1.0, and that adds several more hours to the wait time. Of course if you are most people who just bought a cool new GPS and you want to update the software to the most recent maps (since it's being touted as a great new feature of this GPS), or perhaps you just bought this/received this as a gift, then you probably have no clue what just happened and you think you broke the GPS.Of course the software did not back up the previous map automatically for you, so there is no way to re-set the GPS to "factory" settings. Wow so of course I bought this GPS unit right before going for a trip when I need to use it, and I thought it would be smart to update the maps to the most recent maps before going on the trip.
