DR01 User Guide

The DR01 fits within the shell of an existing classic analogue radio so your car looks exactly as it did when it left the factory - but with the advantage of the very latest in digital technology.


The DR01 should be fitted by specialists since it involves removing the existing radio, stripping out the old analogue electronics, refurbishing the existing controls, making any components required to fit the new digital electronics within the shell, setting up and testing the system and re-installation in the car.

Our recommended supplier and fitting company is Car Electronics Derby Ltd.




The DR01 must be used in vehicles with negative earth only.

The following connections should be made:

  • Black wire - connected to a good chassis negative earth
  • Yellow wire - connected to the battery positive supply (always on)
  • Red wire - connected to the live positive feed from the ignition switch
  • Blue wire - connected to a powered antenna (if fitted)

    Aerial connection should be via a FAKRA connector to a suitable DAB aerial - this may or may not require power depending on the type of antenna fitted.

    Some antennas have built in amplifiers for better reception and require power applied to the FAKRA connector (see the configuration section for more details.)


This is the layout of a typical old vintage radio that has been converted.

  • The left hand knob is the conventional rotary On/Off switch which is also the volume control when rotated further.

    When turned to minimum it also enables other functions depending on which mode you are in - more details below.

  • The right hand knob (Selection Control knob) has many functions and is mainly used to scroll through menus to select what you want and then activate that selection by pressing the knob in towards the radio.

    The Selection Control knob is also used to scroll through the DAB channels and the phone book contacts list as well as auto tuning the FM radio when selected.

Once the Radio is turned on the start up screen is displayed for several seconds replicating a typical old style radio front panel.

After a few seconds the default menu screen appears.

It shows BT (Bluetooth) highlighted and turning the right hand knob will scroll through various options which can be selected by pushing in the knob or by pushing the button under the menu option required.


Whilst the radio (DAB or FM) is playing, or Bluetooth is streaming, it is possible to change the front panel display back to the initial start up screen so the radio looks like the old original radio again.

To do this:

  • press in the Selector Control knob and hold it in for a couple of seconds until the normal menu screen is displayed,
  • release the knob,
  • press it in again and hold it in for another few seconds until the initial start up screen is displayed.

To get back to the normal menu screen, press in the Selector Control knob and hold it in for a few seconds until the normal menu screen reappears.

Bluetooth setup and operation

If required any smartphone connected to the radio can be 'un-paired' from the radio by turning the volume control to minimum at which time the 'UnPair' button is enabled. Pressing this will disconnect any smart phone connected at the time.

To connect to Bluetooth, look for 'ClassicDAB' in the list of Bluetooth devices on your smartphone and connect to it. If you want to use the phone book within your phone, you must allow the radio to access your phone book - see below.

After connection, your music library may be scrolled through by turning the Selector Control knob. Tracks may be selected for playing by pressing in the Selector Control knob.

As with other Bluetooth devices, it is possible to skip to the 'Next' or 'Previous' tracks using the push buttons under the option required as well as 'Pause'/'Play' for the currently selected track.

DAB radio operation

After selecting DAB for the first time it is necessary to scan all available channels. This is done by turning the volume control to minimum to enable the 'Scan' button.

Pressing the 'Scan' button will initiate channel scanning as shown below.

This will show the channel count as it goes.

When scanning is finished, the channel list may be scrolled through using the Selector Control knob. After finding the desired channel, pushing in the Selector Control knob will select and play that channel.

Details of the channel and track being played will be displayed in the main display along with signal strength shown on the right hand side of the display.

You can store a selected channel as a preset using any of the push buttons:

  • When the channel is playing, push in and hold any of the push buttons until the channel name appears above that button at which time it is remembered.
  • Then, when listening to any other channel, this preset channel can be selected simply by pressing the push button under its name.

Please note: channel names are truncated to fit in the text window available and, in some cases, may look strange.

FM radio operation

Tuning different station frequencies is achieved by rotating the Selector Control knob:

  • turn clockwise to scan upwards, increasing the frequency,
  • turn counter-clockwise to scan downwards, decreasing the frequency.

You don't need to keep rotating the knob once the scan has started, the scan will stop as soon as the FM receiver detects a usable frequency which will be displayed.

This may be listened to by pressing in the control knob or stored as a preset to one of the buttons or you can rotate the knob again to re-start the scanning operation.

To clear any preset stations, turn the volume control to minimum and the 'CLEAR' option will be displayed above button 1. Pressing this will clear the preset stations.

Note: during FM reception RDS information may or may not be displayed depending on signal strength and other factors.

External input selection

An external signal source can be connected to the radio via the 3.5mm stereo jack socket on the rear panel of the radio. This may be selected using the Selection Control knob from the main menu.

Phone Book and hands free calling

When the Phone Book is selected, rotating the Selector Control will scroll through your list of phone contacts that was downloaded from your smartphone when the radio was first turned on.

Enabling contacts download on your smartphone

Download will take place only if you have allowed it to do so on your phone.

On an iPhone you need to:

  • Select the Settings menu.
  • Select Bluetooth to see a list of available Bluetooth devices.
  • Check that 'ClassicDAB' is listed.
  • Tap the 'i' next to it to pull up a new screen.
  • Slide the 'Sync Contact' button to 'On' so it shows green.
  • This will enable all your phone contacts to be downloaded each time the radio is turned on.

Please note that this download can take several seconds to complete (depending on the number of contacts you have). During downloading a message will be displayed:

Phone book items downloaded = xxx

where xxx is the number downloaded so far.

After scrolling through your contacts to find the required number, you can dial that number by pressing in the Selector Control knob. The call may be ended by pressing any button.

Hands free

A suitable hands free microphone must be connected to the other 3.5mm stereo jack socket on the rear panel of the radio.

This screen enables details of all calls to be viewed by selecting the relevant option.

  • Incoming calls that have been received
  • Outgoing calls that have been made
  • Missed calls

System configuration options

The next screen enables the powered antenna (the blue wire) and also the FAKRA antenna socket on the rear of the radio to have power applied to it all the time the radio is ON - or, as here, just when DAB or FM is active.

Pressing button 1 whilst in this screen will toggle the selection.

The final screen of the configuration selection is the 'About' screen. This displays the software version that is installed within the radio and the version of the Bluetooth module software installed.

It also details the model of radio set up used within the radio. This may be different to the actual radio model as it is a generic type, not necessarily a specific type.

For example: 'Motorola model 141' will display as a 'Radiomobile model 1080' simply because the 1080 has the same set-up parameters as the Motorola 141.
