Conclusion: I have a Clarion M109 stereo in my boat which, is out of the box, compatible with the Clarion RCB176; I use the remote when I'm swimming or hanging out on the water; I don't have to climb back into the boat every time I want to adjust my music. I mounted the RCB176 just above my swim platform; it's a very handy item own. It works from any angle and from a fairly long distances. I am very satisfied with this item and with Sonic Electronix; I highly recommend both.
Summary: I got this free with the purchase of a HU, and I cannot complain. Only improvement I can think of within this short span of ownership - the folder up / down buttons to browse the USB drive would have made it a perfect one!
Summary: At first I thought this was a ridiculous unit- a remote for a radio that is one foot away, but the controls are more logical and the buttons larger than the head unit,which makes using the remote a common occurrence.
Summary: This is a great, free addition to the radio. Nice to have a mute button. Wish it was on my stereo but at least I have one and don't have to have my arm hanging up towards the stereo. I can relax with my hand on my lap and switch my music with ease.
Summary: Came bundled in package but was a big part of buying decision because I didn't want to have to fiddle with radio while driving. Works great when you learn it. Con: Infrared not RF so it needs to be pointing directly at radio or bounce off reflective surface.
Summary: Got this remote free when I bought my radio. Very usefull when your in the trunk tuning the amps and you need to raise or lower the volume. And like the other person said. Good to have in hand to pause the music when a Cop is spotted...
