Garmin has released a large .jcv file available as a separate download for the 2012.20 map update. It was released for 7x5 series and Zuma 660/665 only. However, I've read several reports where it is working with some other units too, including 1490T. I can confirm this as I now have it on my 1490T (2GB internal memory) and it is working well. You will need a storage card to use this file.
