My Pro 7 lives in a modified tank bag.....I burnt a hole through one end big enough to take the leads both in and out...the only thing right now that I have on-bike is the hard-wired power lead that goes under the tank and terminates on the bars with enough slack to plug into the tank bag in use and wrap around the crossbar discretely when not in use.
The advantages are that I can tweak the settings for input easily by opening the top flap of the tank bag, and likewise the volume on the talkie-walkie, including the channel and volume settings when riding with different people...plus it's an easier install, with no plug ends apart from the power supply to have to leave exposed on the bike.......
When I have the time though, I will wire the unit up to the bike permanently.....the box itself under the front of the saddle where the diag plug lives ('ADV) and the talkie walkie somewhere else yet-to-be-decided......
This will leave me with the problem of how to leave the rider and pillion 7 pin plugs, and the phono/gps input leads.....right now I'm thinking of leaving the rider plug sticking out of the front of the saddle in the centre of the tank with a cap on it or maybe with a few inches dangling to the left of the tank so it's pointing downwards (rain friendly), then doing the same towards the rear of the seat for pillion plug........I'd need to get a pair of metre long coily leads to plug inline to our helmets but that seems like a neat solution.
The stereo jacks for phone, MP3 and GPS are another matter.......I'm thinking of using one of Migsel's speedo ram mounts for this, and putting on a shelf with a small pelican box that will take bothe the phone and the music source (via IP6 Bungs) mounted on the bottom of the box with HD velcro.......this should be fairly neat with the cables running up from the Pro 7 under the tank and up to the headstock, then terminated in the Pelican box.....
This is all to be done though...and for the time being it's easy and convenient enough to have the whole set up in my modded tank bag.
