Hinging on what must be a successful nuvi 360 launch, Garmin looks to be gearing up for the holiday release of the nuvi 660. The 660 just received FCC approval, which gives Garmin the go-ahead to start pumping these things out. Some of the new features cited for this one include a 4.3-inch display, GTM20 and GTM21 functionality (to help with driving during heavy traffic periods), and a super-cool FM transmitter. If strong enough, imagine the ability to broadcast your directions to another car that is traveling with you to the same destination. While cool, we somehow don’t think that this is the intention. Still, we think we will see this one hit retail sometime this November.
