John Bentall Posted April 20, 2006 Share Posted April 20, 2006 The set-up is a Autocom Pro-M1, on-board music on R1200RT, Garmin SPIII + Cellphone , in-ear speakers using Autocom part 27 (or 26 - now 1187). The problem was that even at the lowest volume setting, my ears were blasted by the GPS instructions. Fernando suggested a personal stereo volume control fitted in the circuit and this was duly placed between the GPS and the Autocom input. Ears not blasted any longer, but nor did the GPS instructions now cut the music. A quick call to the help line at the factory. Solution - the attenuator was too effective and there was no longer enough "juice" to trigger the muting circuit in the Autocom. Moved the volume control between the part 27 and the earbuds - problem solved. Link to comment
