HELP setting up Tm150 XSonic on Gen3 HDS 9
I have read quite a bit on this but all of the post are over a year old. I have installed a TM150 which has a black 9 pin connector (actually on has 5 pins in the 9 slots). I tried to connect directly to my Gen3 HDS9 Touch black port and the hds unit does not recognize the TM150!! From what I read, it looks like I need a black nine pin to Blue (standard 83/200 kHz Transom Mount Skimmer) conversion cable (Part #000-13977-001). Then connect the TM150 to the "sonar" blue connector on the back of the Gen 3 hds9.
Am I on the right track?
