ahh... well the fancy blue transponder is an MRTCustom iPT. My old AMB stopped working, so I had it cloned, and now have two iPT's, one in the tourer and one in my mini, both running off the same number
However, I believe the iPT has now been superseeded by the MRT PTX (details
here). Best bet is to ask Terry S over in the PTX thread on here, or send him an email via mail(at)team-mrt.com.
