Following are parts I used to mount/wire up my 2820 on the left handlebar of my bike. If someone has found better sources/parts, feel free to chime in.

part number 010-10495-01The following can be used on both the Zumo and the 2820, or any other 3.5mm output you want to feed into the front of your radio.
From SoundProfessionals, 3.5mm Gold Plated Stereo patch cord:
http://www.soundprofessionals.com/cgi-bin/gold/item/SP-SPSC-7Part number: SP-SPSC-7 (you choose the length..this is a 90degree on both ends, with gold plated contact points...24" will get you from the left handlebar, through the bar openings in the lower inner fairing (use a coat hanger to fish the cable through there...easy as pie and no need to remove fairing). If you want, you can get it in a 3 meter length. This will take the MP3 stereo signal and voice commands from the GPS and input them into your Aux In on the front of the radio. Might as well get two...they're cheap. 90 degree ones are hard to find, so I got an extra just in case. The 90 degree bend looks cleaner on both ends when hooked up, and gets things headed in the right direction.
Then purchase a standard cigarette lighter power adapter, available from Radio Shack, marine supply stores, etc. The marine version will tend to have a waterproof entry for the cord, if you think it's necessary...the one I got from Radio Shack worked fine...just a dollop of black silicone to seal where the cord enters the adapter plug. It also has a green led to let me know it's powered up and the fuse isn't blown. I've not had a problem with vibration, etc. I have this power supply cut to length, so there are no wires bundled up on the handlebars or the back of the unit.
I initially ran the 3.5mm patch cord through the bar holes, fished through with a coathanger...a couple of chrome wire ties hold things in place and excess wire is just pushed into the inner fairing. I now have the 3.5mm run from the unit, through the clutch cable hole in the fairing, then to an additional AUX IN on the back of the radio, so the wire would no longer be visible going into the input on the front of the radio. Installation of this additional aux in is covered elsewhere on the forum for both 04/05 radios and 06/07.
Sorry, but I can't seem to find all of this in one location, so I had to order from seperate suppliers. No issues with any of the above vendors, at least when I ordered.
