Garmin Nuvi 660, picked up on Black Friday for 50% off

Great investment, saves a few minutes per order not having to look up maps online, plus makes finding houses easier and safer as not having to look down at printed map.
Mine has a built in MP3 player, and an FM transmitter. The FM transmitter doesn't work good in my market b/c we have way too many FM stations, so there is alot of bleedover. But I just hooked up one of those old cassette adapters to the external speaker jack, and now it the songs and directions come thru my car stereo.
I can only put 2 address in at a time, and I have to tell it which is first and which is second, thats the only feature I wish was better, I'd like to be able to put more addresses in and it calculate the route.
After buying one, check the date of the included map, mine was actually up to date, so I was able to save my free map update until they put a new map out. Even the newest maps are typically a year or two behind on new roads, took it 2 years to show a new major highway that was finished here.
My unit you set it to find the quickest or the shortest route to a location, so you may get different directions depending on which way you set it. And some roads it just refuses to take me down, even tho I know its a shortcut, and its on my map, it never takes me down them.
