Is there a solution for the low volume from the microphone that doesn't involve spending more cash for a bluetooth interface? Apart from the money, there isn't much space left under my seat, i had enough trouble fitting in the autocom and the toolkit, huge maplin ground loop filter just fits in the space under the tool tray with a spare headlight bulb so i could do without any more extras!
I have the audio out from the zumo via a filtered lead to autocom aux3, and zumo mic in wired to autocom aux1. Everything works fine (except maybe the volume reducing to 50% when I speak, but I can live with that) but the caller on the other end says they can hardly hear me. And there is interference when the engine is running but if the volume was OK i could live with the interference.
I have connected zumo mic to aux1 using the autocom standard phone lead and also made a new lead that only had the earth and mic connected in case the aux1 speaker connection was doing something. i also disconnected the autocom and plugged a skype headset directly into the zumo audio out and mic sockets. It didn't seem to make any difference in any configuration, I could never hear clearly on the other end of the phone. I was testing it by putting an FM radio in front of the mic on the bike end and listening to the phone on the other end which is not exactly a normal call but it should have worked.
What is going on? Is this just crap design on the part of garmin or is there a fault somewhere?
, anyone in the Stafford area fancy helping me out?
