Hello, new guy here. I've been reading as much as I can here, lots of great information. Thanks.

I am wondering what is the best software out now for creating Garmin IMG maps?

I'd like to mostly turn KMZ / KML and shape files into Garmin .img maps for use in my Garmin Drivetrack and Astro 430.

I'm not necessarily looking for free, I'll gladly pay for something that works and is relatively easy to use.
