I'll have to admit that I'm no musician either, but I still like quality sound in my music. I'm new to the LT (1 month and counting), but not to the Zumo 550. I've been using it my Harley Ultra since the Zumo was first introduced and I couldn't ride without it. I agree, having an EQ would be nice, but let's face it... we riding a motorcycle, not sitting in a concert hall. With that in mind, I think the sound is quite excellent. I've transferred all my music from the iPod to a 4GB SD card on the Zumo. The digital sound from the Zumo is even better than what the CD player produces. That has been my experience on both the Harley and the LT. Also, I'm running the Zumo through a DICE converter (removed the 6-disc CD changer) which was designed for use with the iPod. Before hooking up the Zumo, I tested the DICE with my iPod first. The sound quality was the same. I'm like you, I wanted to kill two birds with one stone and the stone of choice is the Zumo 550!
