Question: Is this unit only compatible with Fusion receivers? or will it work with any head unit with an aux input?
Document: Worked great with my Clarion head unit in my boat!!!!! Easy to install. You have to have RCA input jacks on your stereo..
I use this with my ip-600 head unit in Aux mode. My only wish wis that I could see track info on the head unit screen in this mode.
Installed with Fusion Head unit on Golf cart. Works Great with my I Phone. I love it!!!! I am able to play music without all the cords and answerphone then goes right back to playing music!! !
This was easily added to my Fusion MS-CD600. It does exactly what it says, quickly paired with my iPhone 4S and mounts with strong adhesive (already applied to back) if you don't want to screw it into your cabin. My Fusion head is a few years old and was not compatible with the MS-BT200 (which displays track info and such), but not a big deal.
While more expensive than most other bluetooth dongles the Fusion MS-BT100 is far superior. Rather than connecting via a dual mini audio plug this unit connects directly to the amplifier's input jacks - less connections = less noise. As well it is powered by the 12V source so you don't have to have a USB plug which is required by most of the others for power. This also means one switch operation - power on the system and the Fusion is on.
I am using the Fusion to stream music in my 2006 Jeep Grand Cherokee with navigation. The navigation  unit lacks a aux jack. I bought a adapter from Crutch Field that connects to the back of the stereo, it has two rca outputs, and a fused wire for power. I connected the Fusion and now I can stream away. The sound is fantastic! Much better then I expected. Deep bass and crystal clear.
Works great!! I can control the radio in the boat even as far as the beach. No more tethers to the console. And it'll work with any radio that accepts RCA input.
Not a big deal, and I haven't investigated if there's a possible work around maybe with the ifttt app. Bottom line though the Fusion rocks!
This unit worked perfectly. Easy install and performed as promised. Very nice addition to the Fusion radio. A must have
Great for updating older radios for bluetooth. Size was easy to hide in the dash and wire directly to aux port.
Answer: It has an audio jack output so should work on any aux inputs
