Hi,
This is my first post. Was reading this thread and thought I'd share some info and observations.
I've got a 2013 Mustang V6 Premium Convertible with Sync (small screen like in all other posted people's pics, not the big touch one with NAV).
I just had the Masetro RR, MUS1, a backup CAM, and Kenwood DMX7704S installed (by an installer). It looks great. The Kenwood is a new radio that just came out and doesn't have CD/DVD or NAV. It supports Apple Car Play and Android Auto.
My primary reason for doing this install was to get NAV and backup cam display. I got this radio because of Android Auto (which would allow Google Maps to be my Nav), but also price and availability at store I was at. Plus, I never use cd's or dvd's in car since everything I listen to is on a USB stick. Also recently got into Spotify, and this was supported as well.
I've only had it in the car for a few days and driven with it once. I've spent a few hours fiddling with it in the driveway. Here are my observations....
1) Looks great
2) Backup cam integration is great
3) This HU allows for a new Kenwood Dash cam to be integrated. I didn't go for this, but it would probably be pretty cool.
4) I cannot get Android Auto to work on the HU... Could be my phone. There are lots of general complaints posted online from people with similar issues (different cars and HU). Need to further investigate. This has to be the biggest disappointment for me, as it was the primary reason I got this radio.
5) Temperature display on the original Mustang screen is in Fahrenheit, and I want Celsius... Cannot figure out how to change it. Not a big deal, but it would be nice if it were metric since I'm in Canada.
6) I had wanted my original USB port located in the center arm rest to still work with the radio. Right now, I cannot figure out how to get it to see it. If I plug it into one of the MUS1 dash kit's ports, it also doesn't seem to like it. But the ports do work for charging. I assume that the way the songs are organized on the stick is OK since it worked no probs with original Sync system, but that could be an area to look into.
7) I don't understand what original Sync functionality is and is not supported by the HU and/or the Maestro RR/MUS1 integration. For example, I would have expected that my original mic in the car could be used. I find it confusing as to why the installer put the HU's mic in my car. When I try to connect my phone thru blutooth, I see both Sync and DMX7704S as choices. Not sure which I should choose. Been going with DMX7704S. Steering wheel controls work. See 6 above for USB. I guess as a consumer, this is all a very grey area and not very clear. My installer was also not clear on some of it and spent some time on the phone with various support people.
8) A big unexpected issue (and really it's stupid on my part) is how impossible it is to see anything on the screen with the top down and the sun shining on it. The HU doesn't allow you to change the angle. It has some sort of simulated tilt built in that you can set, but it made no difference. Also, the default colors for the indicators on the HU are blue, and I cannot find out how to change them. I has thinking to make them a more contrasting color and it might help, but this HU doesn't seem to allow me to change them. I'm talking about the screen 'on' or highlight color, such as if you turn on something in settings screen, or increase the fan speed on the climate page.
9) The Maestro RR allows you to program what all the buttons do on the steering wheel and the MUS1. Since I don't drive my car in the winter (or when it's cold) I don't ever need the rear defrost. The MUS1 kit has Rear Defrost built in by default and is a waste of a button for me. I reprogrammed it to do front defrost, but it would be nice if you could replace the button.
Overall... I'm mixed on how I feel since so many things are not as expected and I'm still trying to sort it all out.
