Hey guys I have a 2002 xb21 2+2 that has Garmin depth finders and was looking for a replacement that would fit in its place. The one in the dash is a GPS map 178c Sounder and the one up front is a Fishfinder 250c. I was just curious if you know of any units that will fit in these locations. I really don't want to mount them on a ram mount, I would prefer the stock locations. I know this limits me but I was just wondering what options were out there. Thanks...
