You would need the four way connector shown here at Rugged Roads. http://ruggedroads.co.uk/epages/00c...-5d1c-407e-8207-580e14387ec5/Products/SU4P090 and would have to crimp your Sat Nav cables to the connector. Yes, it does power on with the ignition.
This might not be the best use of this power source though. You can buy the Honda 12V socket and this is where it plugs in to with no modifications. You can also buy a Honda splitter cable that splits this power source into two to power a 2nd item, for instance daytime running lights. Again, both on the RR website, part numbers 08U70MJPG50 and 08U74MJPG50.
What you might want to do is use a power block from https://www.easternbeaver.com/Main/main.html lots of Africa Twin specific details and widely acclaimed on this forum (and others). Just use the forum search bar for Eastern Beaver and you will see loads of threads about it and similar products.
