Rich, am I missing something - I was agreeing, an Autocom does not HAVE to be fixed to the bike and has a lot more flexibility.
I may be a Luddite but I still prefer to see good old fashioned wires linking kit together rather than rely on, sometimes dubious, Bluetooth or other clever systems. I cannot see the point iof using radio waves to link a couple of bits of kit that are less than a metre apart and its a lot easier and more reliable to plug a cable in than all the agro. of pairing Bluetooth.
Example.
I have a Garmin with hard wired audio to my Autocom so all I do when I get on the bike is plug in my helmet and, if required, my mobile phone. Takes about 5 seconds. If my wife uses my bike she just plugs in her helmet and phone. No hassle.
Her bike has a Tomtom Rider so needs Bluetooth to get the audio out so its paired with her Scala Rider and, in turn, her phone. I also have a helmet with a Scala Rider. To use her bike I have to go into the Rider set up and wait while it finds and connects to my Scala Rider, then play with my phone menu to get that to pair. The next time my wife uses her bike she has to go through the same hassle to re-pair everything to her helmet. Then I get in my car and find I can't pair the phone to the hands free as, unfortunately, that's Bluetooth as well.
Other problems.
Go out on the bike - damn, the batteries are flat on the Scala Rider so I can't hear the satnav or use the phone. I don't get that problem with the Autocom.
Come home, put away helmet and forgot to turn the Scala Rider off. The next day I find six missed calls on my phone as the damned thing was still paired with the Scala Rider. I have had the same problem turning on a Tomtom Rider to connect it to a computer. It immediately pairs with the mobile so I don't hear it ring.
The only part of my system that has to use radio waves is bike to bike and if I could fix that with about 500 yards of cable, I would.
