Hi, have a look at this site for ideas !!
www.ram-mount-uk.com
they have everything and some.
as for the power, i made up an extention, cigar lighter socket on one end, hella plug on the other. i didn`t want to cut the cigar plug off the power supply on mine. you can get sockets from Maplin for £1. if its like mine ( not waterproof ) wrap it in cling film to keep it dry :razz: :razz:
have fun
