Not an Ipod, 'cos only posy rich twats have them

, but other MP3's no prob......
Take a car charger, strip the connections back, add an inline fuse holder, whack the bare end connections either onto the battery direct or onto the connections on the back of the Aux power socket....job done.
I assume the 1200 has the BWM type plug and socket....you can get them for 3 or four quid from any tractor shop and wire it onto the bare leads of the iPod charger.....centre pin +ve, outer connection -ve.......
The options are endless....up until today when I rewired everything to power some more gadgetry, I had a BWM/normal socket converter on one of my aux sockets, with the female end cable tied to a cross member...I then plugged a normal 12v car charger into that and kept the MP3 player in my jacket pocket, running at the same time as charging.....worked perfectly and will do the same on a 1200
You can also run a power supply to a tank bag or handlebar bag, then wire that to a multi point ciggy lighter socket adaptor thing (about a tenner from Maplins) to charge Ipod, Phone and whatever......
Basic rules though....even though it's canbus, fuse protect whatever you do.....keep the transformers in (I don't spose Ipods like 12v direct

) and keep things as waterproof as possible.......
HTH
PS additional Aux sockets are pretty cheap (less than a tenner) so if you don't have one on your beak, get one in quick....takes 30 mins to wire up

)
PS route all leads as far away from other electrical parts as possible and keep them as short as you can while allowing for tugging...long leads=interferance.
