No, I've got a Navigator IV.

Thanks. Looks not unlike the three (!) that I have. What's the battery life? I have had to add a larger battery to my favourite BT receiver - favourite in terms of volume - because it lasts only approx 8 hours when I'm riding and listening to music continuously. I used these http://earfuze.com/ in my previous (Nolan) helmet but the System 6 is such a good fit that it presses the Earfuze too deeply into my left ear causing excruciating pain. I now use a pair of mini speakers in the lining of the helmet and wear squidgy earplugs. However, the o/p from the BT receivers is too low to hear properly through the earplugs, although the direct connection to the 550 is plenty loud enough to penetrate the earplugs. I could build a slave amp to add to the BT receiver but then it's all starting to get a bit bulky.

Cheers

In practice - I don't know. Most of the time, I can't be bothered with it and just look at the screen. I even took it all the way to California recently where I thought that it would be useful to have voice instructions on the bike in the middle of San Francisco and I still didn't use it.
