I have a Road Tech Zumo 660LM mounted on my bike and connected to the radio through the Harley Navigation Interface Module. It has been working fine for the past year since I installed it. All of a sudden I no longer get voice directions through the speakers. Music plays fine through the Aux connection and the music mutes when the Zumo wants to give me voice directions. The Zumo works fine when not on the mount and the voice comes through the Zumo speaker.

Anyone had this problem? Any ideas on how to troubleshoot the problem to see if I have a bad NIM or bad wire connection (I have visually checked all the connections and can't see any problem).

Installed on 2010 FLHXSE.

Thanks, Rick

 

A wire may have vibrated loose inside your fairing. After checking that, I would contact Garmin.

 

If you have the fairing mount, with the double row of spring loaded pins. Clean the pins with alcohol, and push each one in and out with a small screwdriver. I know this, because the same thing happened to mine recently. This action fixed it.

 

Thanks, I'll give the alcohol a try. I wiped them with a rag and made sure they were all functioning (in and out) properly.

 

Oh yeah...wipe down the contacts on the GPS unit too.

 

I had already sent the following email to Garmin.

Do you have any troubleshooting tips or wiring diagrams that I can use to see if my NIM is defective or a connection has come loose.

This was their response:

Thank you for contacting Garmin International. I would be happy to help with this today. Unfortunately the NIM cable is an exclusive Harley Davidson part, we do not have any installation instructions or diagrams for those cables. To have that cable checked out, your best bet would be to have the dealership that installed it take a look at it for you.


Who needs Garmin when you have this forum. The alcohol did the trick. I had wiped both the pins and the contacts on the back of the Zumo with a clean Microfiber cloth without success. Added alcohol and that fixed the problem. Thanks TriGeezer.

 

I had that problem once. It was that switch on the dash that I moved when I washed the bike. I can't remember the switch but think it was one of the 3 position switches right there on the dash.

 

When I was searching the forum for a possible solution I saw that some had that problem where the switch wasn't in the "speaker" position. I don't have that switch on my bike. I think I read that it is only on bikes that have a CB or intercom.

 

Nice scooter

 

Some people just have good taste
