I've been using a 10 state chip in my truck for coyote hunting, when I went to get an update the company decided to close their business up as it was too time consuming to keep the chips updated. While I'll get a few more years out of the chip. I did try the OnX as a free trial when a friend sent me some coordinates to meet him at for a coyote hunt. I liked it on the computer. I need to look into seeing if they have a chip for the Garmin GPS as both my truck and MC are set up for them for coyote hunting.
