where to mount new depth finder

I currently have a 3 inch black and white at the wheel. I just purchased a 5 inch color lowrance. Should I pull the black and white and put it up front on the trolling motor and mount the new on at the wheel (color), or leave the black and white at the wheel and mount the color up front on the trolling motor. I crappie and bass fish both. Probably more crappie.

I'd put the color up front.

Does it have gps or anything like that? If so id put that by the wheel so you can see it while driving but if not id throw it up front.

Thanks for the suggestions. No GPS . This will make things easier. Only have to mount one not two.
