I have a Garmin nuvi 660, software v.2.30. Have anyone upgraded maps for this version?
I need both upgraded maps and map over greece. Can anyone point me in the right direction for where to find the right maps for my Garmin?
or do I also need to install new software version? I have a 2gb SD card i hope can be useful.
All members that use this device must know that you can use only maps(not SD) <2GB. Dont try to update with a map bigger than 2GB, you will not see it in your Device.

Does anyone know if it's possible to get a Nuvi 660 to show the map after power up without having to touch the "Where to go" on the display? My 765 T does it right out of the box, any tweaks or suggestions?
I’m using Garmin nűvi 660. Bought it in 2008 with North American maps. Back then I also installed couple of European countries and filled the internal memory.
Now I decided to install CN North America 2011 and CN Europe 2011. I will have to buy the SDHC card in order to fit both, so as my first step I’ve installed just American maps.
I downloaded “Garmin CN NA 2011.1” with unlocked image. The files included were:
• D2339010.JCV (48,223 KB)
• gmap3d.img (154,816 KB)
• gmapprom.img (1,286,560 KB)
From the unit, I removed and saved on my PC:
Next step – I copied just gmapprom.img into the GPS unit. All US, Canadian and Mexican maps have been installed – I can see details on the GPS screen.
Now I tried to program the rout. It went directly to the state entry, skipping the country! Since I have US, Canada and Mexico installed it should ask for the country – but it does not!
How can that be fixed?
You should put back the gmapbmap as it's the world base map, also the JCV is not needed as looking at the specs for your device Junction view is not supported
