I recently installed a Starcom sytem and I can't say enough good things about it. Crystal clear sound and it works as advertised. I also want to recommend a supplier of Starcom. Jeff at Bike Effects.com was very helpful with some install issues I had. He even went as far as sending me some Starcom earbuds to try (I was having some engine wine noise coming through, but I resolved that.) Jeff provided some old school customer service which was VERY refreshing. Thanks Jeff. You must go to Bike Effects for your units. You won't be disappointed. http://www.bikeeffects.com/
