Really enjoy mine. Have had one unit about 1.5 yrs and 15k+/-. out of just under 20k miles.
(not much 2 up or group ridding so far)
With one trip from Birmingham, Al to Orlando Fl (no charging needed either way during the ride 9.5hrs?)
and one all day ride from 8 am until 10:30 pm from home to.
Well all over Knoxville, Chattanooga Tn. area.
Including the Dragon. 1st and only Dragon ride so far.
I did have to charge at the end of that day.
Say 10.5 hrs run time.
I did order a the mount with the ear bud jack.
I um..
Well see, I set the helmet on the seat and the ground just reached up and grabbed it..

busting the mount.

well, I doubt she bought it either, but I did get the new mount.
(sadly, it is what happened ,you would think I'd know better at 42)
Actually was already looking to order the ear bud version any way.
I have been using the JVC ear-buds with marsh mellow tips for $20. since.
The sound is clear and loud enough to hear at highway speeds.
Much as I would like to have better buds.
Well... I break them to often....

I use a 80gb Ipod classic for tunes using the aux. jack with good result.
I like the battery life of the iPod and mega space for tune, audio books, and such.
That and it save me either having to use a power cord to the bike or a draining the phone.
Phones:
I have used the unit with a Blackberry bold (good control of music player and phone including voice dial).
Android Samsung, same good control and phone use, did not try voice on this one.
Now using Iphone 4 and player controls are OK, Voice control is nice).
It even beeped 3 time when the boss sent me a text to stop and pic up taco fixins for tomorrow.
Had 0 clue why it beeped at me

. 1st phone to do that.
I also want the

This would give about the most flexibility in frequency choice I can think of so far.
For group riding or for our annual beach trip to St. George Ilse, (east point, FL)
