Just did this on my 07 PIV. As BCB says, purchase their custom bezel, a mounting bracket and a Y cable from HB. The Y cable permanently splits the SI transducer and 2D transducer (in the bilge) and routes them to the unit. When you remove the old GPS puck, leave the hole there till you are finished. It is a straighter shot to feed the cables. You will need to pull 3 cables (GPS, SI transducer, 2 D transducer). I also removed the Air vent on that side which made feeding cables easier. Tape three pieces of heavy monofiliment (string trimer line) to the old GPS connector under the dash. As you pull it back through, you have a line to use to pull the new wires. Go easy; they will tend to hand up. Pull back the opposite direction and keep going. Use one line for each cable you have to pull, I think this was easier. You can also use the old Lowrance ducer cable uner the dash to pull a line the other direction if you want to remove that ducer. Place some tape over the sharp edges of the connectors, expecially the new ones to reduce hangups and prevent damage. Worked ok for megood luckjwt
