Hi Dan,

That is a very bad idea! The RJ connector on the back of the 302 is for
connection to the 303 LCD display. The 303 is a low voltage device. Your
Mio is not. I'm not certain, but I fear you will fry something in the 302.

Best Regards,

Paul Remde

While I had my panel apart the other day, I noticed the RJ jack in the
back of the 302. Since I had half a Cambridge cable, I plugged it in,
powered up, and measured voltage across the red and black leads - 5v!

I took a standard USB cable that fits the Mio, cut it, and measured the
red and black leads - again, 5v! Tomorrow, I'll connect the two cables
together and run the Mio of the ship's batteries.
