Dave Garmin has a AUDIO GAIN adjustment you can control. Good news. Not sure if you model has that gain or volume, but do know some Garmin audio panels do.  ANY WAY Garmin (some models) are adjustable. Some req you go into a menu. 

   

  Other intercoms that don't have adjustment can benefit from a headphone amp or small preamp to feed the intercom. iPods and CD players have small amps that are made to drive small headphones or earbuds. They tend to be a little under powered to drive some intercoms. Also the output from portable music devices is 16-32 ohm impedance. The input impedance to most intercoms is 600 ohms. The mis match does not help either.
