That is where I purchased mine from. Comes with everything you need to hook it up. Extremely fast shipping. I was told if I wanted on plane depth reading I would need some additional equipment, but mounted correctly mine works fine. I however did purchase a seperate ducer, mount and power cable and mount one at the dash and one up front. This way I can switch the head unit back and forth. This will do until I can get another head unit. I've got some good install pics if you have any questions let me know, I'll try and help.
