Tim, having been wired for years on my RT-P, I had a very hard time without. The Autocom system was good and pricey, and i still use it. However, you did not metion what you riding partners ride or what to use for comms. Most systems are pricey, bluetooth is cool but the run time can be short, even shorter the more you use them.
I resorted to budget minded, low investment, high return with an unlimited number of users, unlike some systems only allow 2-4 users on a link. IMCmoto.com out of Costa Mesa, Ca. offers a headset system for around $70. This unit plugs into a simple FRS/GMRR type two-way radio's that can be had for as low at $30 per PAIR with rechargable batteries. Most of the time bike to bike comms are short distance (half mile, line of sight).
I've had as many as six riders on multi day trips comm linked via this system. We've been very pleased with the results. Even the stock BMW systems will support a FRS radio. The system comes with earphones, boom mike and PTT with related wiring. Lowest cost that I have found and will fit everyones budget and equiptment. PTT operation is best, VOX is problematic at best on a motor, can be workable but wind noise is a chanlange.
