I just suddenly lost sound on Sirius, FM, or through my phone. Tried to raise volume but, it’s stuck on 14. Went to settings and tried to increase bass & treble but, it immediately reverts to flat response. WTF?

 

First action:

Disconnect the battery ground cable for 10 minutes, then reconnect (and reset the auto-up power windows).

Post back w/results.



Flaky things happen to Jaguars when battery voltage drops, but they will usually start OK...

I know on other older models, like ours, you can reset the head unit, BUT corruption issues usually arise when voltage drops.

 

I don’t think it’s a voltage issue. Parked the car and was in a store for 10 minutes and came out to silence. Was going to try and disconnect the battery when I get home. 🤞🏼

 

Thanks for the reply

 

Just got back in the car after a Dr’s appointment and it’s fine. Go figure. Jaguar being a Jaguar

 

Jaguars often self-heal.

 

wish I could

 

...and when they do THAT, its often a sign of intermittent low voltage.

Have you had a chance to disconnect the battery yet?

 

No need. Audio came back on its own

 

What he was saying was electrics gltches are often due to voltage issues.

 

or, the notorious Jaguar electrical system

 

It happens from time to time for no apparent reason. I think the IAM gets confused sometimes and freaks out.
