Re: Volume output of Zumo 660
This is late, and you may already have the volume problem solved, but. . .
Boosteroo works OK but comes with a number of issues, not least of which is that it needs to be modified to power it from the bike. And of course it gives you no control over the gain. The Amplirider solves all of those problems, works great, and is jewel like in its quality.
I have one between the Zumo output and the aux input on my '05. The variable gain allows me to match the Zumo precisely with the on-board radio.cd player so that I don't have to remember to reduce the volume when switching back to the radio. Great product, very well made, and very well supported by the fellow who hand builds them.
BTW, if you want a boosteroo, I'll send you the one I tried for the cost of the postage. Email me.
