VISEEO Mercedes MB-4+ OEM Bluetooth adaptor with 5v USB charging Port

The Viseeo MB-4+ replaces the MB-2, and has many new software and hardware improvements. The MB-4+ is now powered by a Bluetooth module from Parrot, the industry leader in Bluetooth technology. The MB-4+ also features a clever multiple pairing mode, which allows up to 4 phones to be paired at the same time. You can easily switch between which phone to use with the car kit by the press of a single button. The MB-4+ also features USB charging which will allow you to charge any mobile phone via a USB charger.

Once paired, your phone will automatically connect everytime you turn the ignition on. When a phone is connected and in use the MB-4+ will mute the radio system and the conversation will be conducted through the cars existing speakers and microphone.


Using the MB-4+
The ViseeO MB-4+ is designed to work in all Mercedes vehicles with the UHI (or MHI) connector. You must have this connector in order to use the MB-4+ . The UHI connector is generally found in cars made 2005 onwards, however can be found in earlier cars. The MB-4+ simply clips onto the UHI connector in your car and you are ready to go. The UHI connector can be found in the centre arm rest of your car or sometimes on the dashboard.

Sometimes the UHI connector may be under a black plastic cap, or it may have a detachable phone cradle from Mercedes connected to it. Once this has been unclipped, the MB-4+ will plug straight into the UHI connector.
A photo of the UHI connector can be seen in the compatibility section.

Classic features
Like its predecessor, the MB-2 Bluetooth upgrade adaptor, MB-4+ is free installation device. Simply plug MB-4+ into the UHI connector located under the front armrest and you are ready to make a call via Bluetooth. MB-4+ will automatically upload phonebooks from your mobile phone into Mercedes Comand console. You can dial out or receive a call simply by pressing the buttons on the Comand console or the multi-function steering wheel.

Premium functions
MB-4+ uses the new CK5050+ Bluetooth module supplied from Parrot, a leading Bluetooth handsfree company based in France. This particular module will equip the MB-4+ with extremely fast phonebook sync performance, excellent phone compatibility and brilliant sound quality.

MB-4+ has also added a Bright OLED Screen like its premium brother MB-3 that not only allows us to design a simpler user interface for a smooth operation but also allows us to add more features to it.

The MB-4+ comes with a 5V Charging Port that enables you to charge the battery of your phone or iPod or any other devices that can be charged via a computer USB port.

With the MB-4+ you can now pair up to 4 phones and each holds up to 1000 address book entries and total up to 4000 entries.

  • SYNC Now Button is a short-cut command that allows you to sync phone’s contact at anytime with one press of a button.
