I have a 76csx. Bought it last summer when Garmin had a $100 rebate. I actually got that rebate too.

I bought it initially for a trip to NC and just wanted to make sure i didn't get lost.
I live in Avon,CO and I would like to upgrade the unit to do more for me. I was a little turned off by the lack of any real included maps and haven't really used it since.
Could you recommend some map software for my computer as well as some maps that work well with my unit. Basically any advice as to what I could get to supe it up a bit and really start to map some of my bike rides.
Don't hold back!
