I have a motorguide tour edition trolling motor that is pinpoint ready and I recently purchased a used Pinpoint 7220 sonar display. When I got the display I noticed on the back that there are two 9-pin connectors, one male and one female. The connector coming from my trolling motor is a male which fits perfectly in the female plug on the display. However, the display will not power up. Is this other (male) plug on the display for power? The display didnt come with any cables but even if I get a power cable ($50) will this display be compatable with the transducer in the trolling motor?
