I’m sure it will fit. I’ve got a HB 1197, which is comparable size, on mine. Mount with a big ram mount so you can move it around a little to position just right. My local dealer has actually put HDS7’s in dash on the WX2100 with a little extra cutting.
You wont have any issue fitting a hds 10. You will want to put it on a ram mount for sure and try it out before screwing it down. It will fit without a problem!!!
