The functions autotadio / CD are classic, with a relatively clear menu structure and useful settings (such as listening position - quite impressive) or nice (as the choice of display color).
A defect concerning almost all car radios 1-Din market: the knob is left of the display, you can not see the screen when handling the (annoying to select what we want) - especially if the radio is located high enough in the dashboard.
One advantage, the device comes with a separate microphone with a sufficiently long thread that to mount it in the ceiling.
The Bluetooth functions work flawlessly. The ability to transfer its phonebook and four programmable shortcuts to frequently called numbers greatly facilitate the use hands-free mode. The sound is good, and the caller hears clearly. Ergonomics is certainly better, however, with the steering wheel controls (which I do not have).
The App Remote function on an Android phone works fairly well. I can simultaneously listen to streamed music from my phone, the GPS and alarm-prone areas.
The limitations come instead of Android:
-I have not managed to get reading high voice sms
-The applications running in multitasking show the screen when an alert (eg radar.), but do not make it to the original application (eg gps) - you have to press the phone's Back button
-The navigation between the tracks works for the Deezer application, but not between albums or playlists: you have to use the phone to change the album. Despite Remote App, access to the phone is always required to operate some functions, like changing album on Deezer. If you only want to use the telephone functions, the phone can stay in against in your pocket.
-the volume of different applications is not individually adjustable
-and finally, the most annoying: can not listen to the radio (on the radio) and have the GPS guide (via the telephone) simultaneously: the radio will only read one source at a time. We must therefore listen to music stored on the phone to the same time have music that gps guidance.
CONCLUSION:
I do not regret this purchase, although the ergonomics and functionality are not at an original system. I have indeed given a sacred facelift to multimedia connectivity of my car for a price ten times lower than that of an integrated system (it is also impossible to mount after the fact, in the majority of case).
