## Questions & Answers

**Q: Will this fit in a 2012 subaru outback with no problems**
A: Yes, it should.  But the controls may not be exactly how you want them.  E.g. the up and down station may be a search function instead of going through your preset.

**Q: will this work with the steering wheel, phone pick and hang up blutooth buttons?**
A: My buttons are the simplified version, no phone. But it does work great with volumen, mode, mute, track. I few times it has not work, but it seems that after I turn the car on again, the problem is fixed. Hope it useful info for you.

**Q: Will this work on 13 Impreza base model without Nav?**
A: I put it in a 2014 outback

**Q: Comes with manual and works with steering wheel control I assume?**
A: Yes it comes with a manual.  I was successful in wiring to my 2013 Subaru Legacy.  Steering wheel controls for volume and channel.  The manual covers dip switch settings but  I had to play with the dip switches a bit to get it all working. All in all I am very happy with this product.
