Hey Zooks,
I assume you’re talking about the 1866310 pn, which has been discontinued. I stumbled on the following item from Northland Marine in my pursuit of an 1866310. https://northlandmarine.com/products/minn-kota-pd-v2-to-bt-ipilot-upgrade-kit-fw-2774155-pd-v2?_pos=2&_sid=e1a0b9a01&_ss=r
It’s actually a bluetooth head for the PD V2, and it replaces part number 1866310. It is bluetooth enabled so it supports the new ipilot remote, the mobile phone app, and the minn kota heading sensor for using the jog feature in i pilot.
Install was super easy, basically remove the old head from the shaft, put the new one on, route the cables and you’re done.
This is seriously the best money I have spent on my boat yet. I was on p4 a few weeks ago with water levels over 12ft and moving at over 100,000cfm and it held up all day.
Feel free to reach out to me if you have any questions!
