Can anyone direct me to site/thread with solution or provide recommendations to solve the following problem?
Problem: Zumo550 does not put out enough volume for me to hear through the Autocom to in-the-helmet speakers. This is with both the Zumo set to 100% and the Autocom set to 100%. I've found a few threads that concluded the volume out on the Zumo was "wimpy". I concur completely. I have 4 weeks to sort this out before my June trip of appx 7K miles to pacific coast, so I'm motivated to solve!
Goals were GPS with voice prompts, MP3, XM for future, bike to bike for future, and intercom to girlfriend (also married to her for 35 years!)
a. 2004 1150RT
b. Zumo 550, mounted on RCU shelf. Garmin's motorcycle mount ("docking station") current on hand built bracket while waiting for TOURATECH's Zumo motorcycle mount which is on backorder.
c. Autocom Super Pro AVi Kit 300 Duo.
d. Zumo to Autocom cable part# 1299 which is two cables from Zumo (mic in and stereo audio out) to one cable for Autocom Aux port #2
e. Autocom's standard helmet speaker/mic that came with the duo kit.
Contributing factors to the problem are I have some hearing loss and wear a good ear plug to cut the wind noise in my HJC Symax helmets. Since my bike is torn apart for installation I confess that I have not road tested my current configuration. Although the Autocom will increase volume with road noise, since I do not get enough volume even at max on Zumo and Autocom while sitting in the garage, I can't imagine that auto volume increase will solve anything. Having no room to adjust volume up just can not be a good starting point!
Possible solutions seem to be an amplifier between the Zumo and Autocom, or in-the-ear speakers. I don't want to ride without the ear plugs and not real interested in in-the-ear-speakers because of the (perceived) hassle of putting wire plugs in ears then pulling on helmet etc. So amplifier seems to be easier way to go.
Does anyone have advice for me? Will amplifier solve the Zumo volume problem? Is in-the-ear a better solution even with "hassle"? If in-the-ear how do you wire from helmet to autocom since still need wired mic output from helmet? Recommendation on amplifier? Anything else that you think might be installed wrong?
Thanks for help in advance!
