7. Troubleshooting

1. INTRODUCTION

The Smartlink

 from Dension is a vehicle and head unit specifi c kit, 

giving you a 

brand new user experience on your smartphone

 with 

MHL connection

. This cutting edge device allows you to see the exact 

same content on the car display as you have on your phone and gives the 
possibility to control, browse, run applications, watch videos or play music 
from the connected phone. 

Other devices like iPhone or iPod touch can also be connected to the 
Smartlink (

special adapter 

is

 required 

e.g. 

Lightning Digital AV adapter

 

for iPhone 5s / 5c /5) but without control option from the radio. 

Smartlink has one additional video input where external video capable 
device(s) can be connected like a DVD player, rearview camera or others 
with external video output.

Supported MHL capable phones

For the latest compatibility please visit:

Please note: 

The MHL capable phones produced by SONY (e.g.: Xperia Z,

by all radio systems.

2. HOW TO CONTROL

The Smartlink adapter comes with a Remote Control Panel (RCP) what 
you can use for browsing, running applications and to 

accept, hang up

 

or 

reject

 phone calls.

3. VIDEO FUNCTIONS: 

With the Dension Smartlink Universal Mirroring Interface can play video 
from other sources like portable DVD-player, rearview camera, etc. 

There are 

2 different video inputs

 available on the Smartlink interface: 

one with video and audio-in on the connector port (recommended for 
portable playback devices) and another one with video connection only 
(recommended for rearview camera).

The video source on the Connector Port can be selected if there is 

no 

device connected

 to the MHL/HDMI connector. You can 

toggle

 between 

the 

MHL/HDMI 

and the 

video

 only input by 

pressing button ‘B’

 on the 

RCP.

Please note: 

Using this video input through the Connector Port 

requires

 

an optional 

video cable

  (

EXT1ICO

) which has to be connected to the 

Connector Port’s AV-in. The playback control is possible using the 

UI of 

the connected device

 only.

4. PHONE FUNCTIONS

Turn ON the Bluetooth option on your mobile phone, search for available 
devices and select ‘

Smartlink

’.  The phone will be automatically 

connected because no specifi c PIN authentication is required for the 
Bluetooth connection. You can see the connection status on the phone’s 
screen if the phone is connected.

The phone option of the Smartlink is available only if TV function is active 
– e.g. the system is in Smartlink mode. If you have an incoming call while 
different source is selected (e.g. Radio, external video), switch to Smartlink 
mode before accepting the call.

You can 

answer a call

 by pressing the

 ‘SEND’ button 

(music or running 

application gets muted) on the Remote Control Panel. Press the 

‘END’ 

button

 to 

hang up

 or 

reject

 the incoming call.

6. Tips and Tricks

Using the applications in 

landscape orientation

 on phone is 

highly 

recommended

, although that feature is not always available. Therefore 

an additional application might be required to use the selected app in this 
mode. There are certain apps for that e.g. Ultimate Rotation Control, Screen 
Rotation and many more. Using these applications above can signifi cantly 
improve the Smartlink browsing and user experience, however these 
force the display to appear in landscape, therefore the displayed content 
might not be optimized. Alternatively 

visit Google Play

 Store and try other 

applications if your current application has no Landscape support.

Turn ‘

Smart stay

’ or ‘

Stay awake

’ option (the naming is phone dependent) 

ON to 

disable 

the

 automatic screen lock

 option temporarily. 

Deselect ‘

Split Screen’

 option and 

turn 

the 

ZOOM

 option 

ON

 in order to 

get 

bigger display

 size 

on

 a 

CIC Professional

 System.

There are certain applications developed and created for in car use. Use 
those app to achieve greater control and better visibility in your car. We 
recommend the use of ‘

Car Dashdroid

’. According to our experience 

the most functions and features were accessible with this App, however 
there are several very good and useful applications that work well with 
the Smartlink.
