Do you have one of the early vintage Garmin
GMA-340 audio panels and have been struggling to hear your IPod or XM-Radio or
other Aux In audio device?
Well join the CSOB Club because that's what I
have. It's a GMA-340 with no mod levels completed on it, which means it was one
of the early units. For whatever reason these early units did not have a good
audio volume amplification when connected to popular audio devices. Later model
GMA-340s were set up with a user/installer configurable 10 or 20 db increase of
amplification volume via the pin outs.
After not being able to Rock-Out to my
favorite tunes on long trips, I found what I believe to be a great little
solution. The $30 Boostaroo!
This little unit takes the volume of my
Weather Box with XM Music or
and pumps it up 12db which gives me a level that I can enjoy through the Lightspeed
Or, try the Boostaroo revolution, pictured below, for about
a 22db gain
Here is a picture of the older Boostaroo model mounted
just above my Garmin 376C CSOB Weather Box. It's simple to use, has great
fidelity and takes two AA batteries that have lasted me 3x the length of time my
headset batteries last.
