Anyone any recommendations to tapping into a 24v source under the dash for a aux socket to run my sat nav?

Kinda broad of a question. Is the sat nav 24v? Are you going to need a fully powered circuit, or only switched on circuit? Or both?

Sat Nav runs on 12v or 24v.Can be fully powered,nothing to stop me putting a on/off switch in the circuit.

The way I have added extra 24 VDC circuits is to install a circuit breaker downstream from the existing one on the firewall. I added one for my backup lights and one for my yellow beacons. Being that you want to install something electronic, I would fuse it down to what ever the manufacturer recommends, as the smallest (mil-spec) circuit breaker you can buy is 15 amp.

you can pull power (+24v) from wire #27 under the dash... same wire that powers the gauges and stuff. It will only be energized when your main power switch/lever on the dash is on.
Obviously you should only go this route for a small add on accessory and still fuse it and stick with 14 gauge wire up to the fuse for sure. Any large loads should have their own circuit to the battery/distribution panel. Or you can get one of those larger solargizer kits that has the distribution box and multiple fuses & circuit breakers (below pics show my solargizer setup).
