Can someone help me please, I have a 2002 X-Type sport with the full sat nav touch screen but I am now down to only one rear speaker working. Have checked all the obvious settings/balances etc its looks like the others have just died. When the jag was in for a service not too long ago I montioned this to them and they said 'Sounds like the head unit channels have gone' unless you have 5k to replace the entire unit I would just learn to live with the one speaker...is this right?

 

There are certainly much better ways to diagnose the system than what the dealer did.

To diagnose a blown speaker, you need to take off the door panel, remove the speaker, and connect a known good speaker to it (even a house one for a test will work) just use a length of wire and hold the wires to the connector with the radio on. Dont let the wires touch each other of course.

I really cant believe that the dealer wants to sell you a new NAV unit.

If I had the time, I would take the door panels off, mark the speakers with a permanent marker. Also take the nav unit out of the dash and mark the back of it.

Have them do the suposed 5k repair.... and catch them red handed at screwing you......
Of course they wont call you a good customer anymore hahahahah.....

 

Thank you all very much for your quick responses...summarising what you all said, I agree with what you said, it should either all work or all not work in the case of the amp etc. Another suggestion posted below is to replace the speakers I think this is probably the best starting point especially as if I take it in I will get charged for them to test it...may as well spend that on the speakers first.
Thanks again great advice.
