I have had the Zumo 660 fitted to my 2010 Spyder RT - S
I have found there was some buzzing from the MP3 Player on the ZUMO on to the Spyders speakers
This may be because both the Zumo and the Spyder is powered from the bike
Essentially if both devices are powered from your bike.
A ground loop can exist that will cause humm, static, or some other interference in your audio signal. A ground isolating cable eliminates that interference.
I understand this problem is called an earth loop and can be solved by using an isolated music lead
I will get one from Autocom and try it
I tried the Isolated cable and this did reduce the Buzz but I was also getting intermitten audio (keeps cutting out)
the Zumo was fine on Bluetooth with no loss of audio signal
Having checked the system I believe the fault lies with the RT Wiring Harness used to connect the Zumo into the existing
Audio system (Multi Plug with the 3.5mm stereo plug which fits into Zumo 3.5mm socket)
This appears to be Shorting out at the Multi Plug end where all the wires combine This is sealed and cannot be fixed
I want to order a new Harness but can only locate it in the 2011 Parts, Accessories and Riding gear catalogue as part of the
GPS SUPPORT AND HARNESS kit Page 37
I don't need the full kit e.g. Bracket, Rubber boot etc Just the harness
Anyone know the Part number so I can order one as a replacement
Any Information useful
