Please note that code entry is only possible when "--CODE--" is shown in the display. If the display continually shows "WAIT" then the unit may be codelocked and will need to be left switched on up for up to two hours to reset before another code entry attempt is possible. If it does not reset after this time, then all of your code entry attempts may have been used up, and the unit will need to be sent to us to be decoded and reset. Please contact us for the cost of this service.

If you have lost your radio code, we can supply the Security Code for this Radio using our online E-Code service. Simply submit your Radio details via our online form, and then sit back and wait for us to E-Mail your Code number back to you.

To remove the Radio, you may need to dismantle some of the centre console, or side covers for access. Please consult your service manual for details on how to remove this panel. The leads can then be unplugged.
