Garmin 2820 Aux Port Help

[ehaughn]

I have a 2002 KLTE. I would like to listen to MP3's and XM using the Garmin 2820. I am using a 3.5mm stereo cable. As soon as I plug in the cable to either the Garmin or com system, there is a loud constant humming noise. I tried using Garmins different mode, headphone and line out, neither one worked. I also tried using the Garmin 2730 with the same result. Not sure what is the issue. :mad:

Anyone out there with a Garmin using the Aux port on the com system? :confused: I have the BC3.

Sounds like you need to get a ground loop isolator, check at Radio Shack or

With my autocom I used the their isolator and had no problems also.

What kind of isolator did you use? Where did you install the isolator?

Autocom sells a cable with a ground loop isolator built in, that should also work,

I tried the ground loop isolator on my Garmin 2730 and it fixed the issue. Unfortunately, it does not work for the 2820. It improved the quality slightly.

Any other suggestions?
