I purchased my boat from dealer stock. If I had it built I would have opted for a factory installed sonar.....but now I need to install myself. Any suggestions from Bennington on routing and getting the sonar cable from the dash area to toon, I think I only have one mounting bracket and it's on the left toon. I wish it was on the same toon as the helm side, that just adds some extra length and routing work. The boat is in the water. so it has to be done beached or in the slip. I crawled inside the helm, lost of room in there to work....it's just snaking the cable from there to the stern I think will be a pain. Suggestions welcome. BTW, I plan on flat mounting to the dash , and thankfully that part looks easy.
