Thread: City Navigator North America NT 2011.20 USA+CAN (MS with Mexico+IMG+ JCV+3DBuildings+timezone)

Hello all. I've got a nuvi 660. The current MapSource (6.16.2) with patches is installed, along with City Navigator North America NT 2011.20. What's the easiest way to install 2011.20 on the nuvi 660?

If it helps, I do have GarminUnlockerAlternative v5.5. But could I also use MapSource? I heard there may be some issues using MapSource though?

EDIT: Nevermind, got it figured out. Ended up using GarminUnlockerAlternative for the nuvi 660 using the updated gmapsupp.img file. I'll just be using MapSource for GMXT on my PPC/phone.
