This popular stand alone navigation unit is found in many variants of VW models , it’s also fitted to Seat and Skoda vehicles.
It has a built in amplifier and later version have DAB tuner as standard
This unit has a 4 digit pin code ( which we can supply ) – once activated it pairs to the vehicle – and won’t need set again.
These units suffer from various issues , mostly to do with software . This causes a ‘constant restarting ‘ of the system ie. splash screen displaying over and over again. Other issues are ;
We replace the faulty components and reprogram with new updated software – as well as this we supply a new updated map , speed cameras ,video in motion activated and also a replacement code ( if required ).
First of all the unit is disassembled and inspected and also electrically tested on our jig. The board is then cleaned of all corrosion and the factory applied protective coating is removed. The board is inspected in closer detail.
We use factory sourced production line components to ensure the sound quality is as precise as a Bose should be.
Finally, once assembled – the unit is reprogrammed and updated
Lastly we coat the unit with a hard plastic sealer – we do this to protect the circuit board and modules , this won’t make the unit completely waterproof but it does give the delicate parts excellent protection against water / salt.
We recommend fitting a cover (now supplied by Audi – at around £10) to protect the unit from any road spray .
Occasionally we see units that are beyond repair , this happens when one or more output modules fails to a dead short across the supply rail . As there are no fuses in the unit , the circuit tracks superheat causing the board to burn out – sometimes even catch fire.
It is not possible to repair or safe to attempt a repair when this happens – the fibreglass circuit board becomes conductive potentially causing a fire.
