## Questions & Answers

**Q: What are the dimentions of the unit?**
A: 3 to 3.5 wide 1.5 tall. I love mine. 
I have bought 3 others. None had a off button all were to bright. This one change the color to red and all is well. The hands free phone is wonderful.

**Q: Does aux port support output eg. aux out?**
A: The Auxiliary (AUX) port is a standard sized plug in jack. It takes incoming audio from for example, your radio or tape recorder or phone so that it can be broadcast to your car radio to play out through your car speakers.  So to summarize, it only takes audio in, it does not put audio out.

**Q: Will this unit outpost to aux?**
A: the aux is for input NOT output. The output is the FM station you sync to.

**Q: Doesn't fit in my cigarette lighter - trying to install in a 2000 porsche boxster. anyone find a workaround? it just pops right out.**
A: You have to push it in really, really hard & it will suddenly snap & stay in. I already had a lighter adapter that expands your 1 outlet to 3 outlets. The plug for that works just fine in the lighter & then I plugged the unit hard into the adapter. That way if I can't unplug it, I'm covered!!!
