Have just fitted the bluetooth upgrade unit and made the connections to the old 54-pin connector and the MOST cable on my 06 Td6 but the display is showing 'No phone fitted'.

I've checked that power is getting to the unit so have I missed another connection somewhere?

How do I check if the brand new module is faulty?

Many thanks

Thats what it says on mine when it is not paired with the phone.

Try pairing the handset, from the handset and you should seen the phone on the screen. There is nothing that can't be fixed with a hammer😜😜

Of course! How dim am I? It even shows that phrase in the handbook.

Many thanks
