The "point 1" runs to a backbone that is a series of T's from nmea starter kit. 1 nmea wire from front unit and another short nmea wire to back unit if its close enough to reach unit on console. In all you need 4 T's if you hook up two units.

Two T's come with the nmea starter kit and one T comes with "point 1 antenna". You will need one more T to make it work with two units.

You will have a T for each unit and one T for antenna and one more T to run a power to backbone (switched) to be able to turn off when not in use or battery will run down.

The antenna does have to have a hole in deck for wire to run to backbone and should not be mounted by trolling motor or big motor because of the compass. Mount it by console to keep it from interference from motors.

Takes about one hour to hook it all up and then go into menu to turn on point 1 antenna to each unit in gps settings. Once thats done you need to configure antenna when you get on the lake by making a large circle.

Hope that's clear enough...It's really simple and easy.

Bobby, Don't come without plenty. Brand not that important.

What'd you say your address was Benny? I'm thinking the only place the module will fit on my Stratos will be right behind the driver's seat. That'll be 3' or so from the motor. Also, the HDS8 on my console will be the only unit connected for now.

I ordered my point 1 and NMEA starter kit. In the future, please stop pointing out gadgets that I don't have. It's much cheaper if I do no know about them.

I know Bobby can relate. BTW Bobby, I have some baits that you don't own yet........
