Very good Bluetooth

// --------------------------
// BLUETOOTH AUDIO
I bought this unit only for use in "Bluetooth Audio" with my phone (Galaxy S3 Android 4.3).
And it works wonderfully.

Pairing is done as with headphones: from the phone by simply clicking on the name of the car radio (152 CE) from the list of available Bluetooth devices (without verification code).

Once paired, the phone can be stored in the pocket and in standby mode.
The radio remote control for changing into your phone.
The "previous" buttons "next" and "pause" the radio sending shares the phone.

After cutting the contact when you will head in car music will pick up where she left off; without having to touch a button on the telephone or the radio.

Small disappointment: MP3 played Bluetooth information is not displayed on the car radio.
I do not know if it's because of Android, the Bluetooth audio standard, or the radio.

But information appear without problem with the SD card, judiciously placed behind the detachable front panel.
Or from the USB socket on the front, protected from dust by a sliding cover (rare).

// BUTTON "Max sound DBB"
The "Max DBB sound" (bottom left) is a real good surprise.
It is a kind of "Loudness" or "Bass boost", really super effective.
Effective to the point that I no longer plans to change my speakers, yet older than 10 years and fitted as standard.

The only negative is that when you use the GPS in your phone at the same time as listening to MP3 bluetooth (with the "max sound dbb" engaged), the way of directional guidance is really powerful (too).

Unfortunately for now, with Google Map Android 4.3, it is impossible to decrease the volume of the application in relation to the overall volume of the system.
The solution is to disable voice guidance.

// --------------------------
// TELEPHONE CALL
The numbering of phone calls must be made from the phone.
The unit takes over to deliver the call to the speakers of the vehicle, and incorporates a microphone.

There is no exchange of the list of contacts between the phone and the car radio.

A button on the unit can hang up.
In case of incoming call, the same button to get (or not).

I made a test call using the built-in microphone on the unit, with a vehicle "essence" relatively well soundproofed (VW POLO 2001 windows closed).
The caller could hear me.
Even if the phone is in the pocket, the microphone incorporated in the device is enough.

On the radio, the "phone" lets just call the last number dialed.

// --------------------------
// GPS
If you use your phone as a GPS navigator and you connect to your car stereo bluetooth, voice changes direction ("turn left", "turn right", ...) will be broadcast through the speakers of the car.

If at the same time listening to MP3 Bluetooth (from your phone), voice direction changes will automatically pause the music, and resume later.

// --------------------------
// QUALITY PRODUCTION
The build quality is really surprising for a car radio of this price range.
The control panel does not vibrate, adjusts to the millimeter, and its finish is good.

// ASSEMBLY
I have the advantage of owning a car not too old (2001), with 2 big catches to current standards.
One branch, and it works.

Watch in hand, the radio change took me 4 minutes.

CD drive of absence allows to halve the depth of the housing.

NB1: The supported SD cards are SDHC standard.
NB2: The "pause" button is the No. 6 favorite radio ;-)
