I have an 05 tl/nav anthacite with 900 miles.
My system is stuck in hfl mode.With the car off and key out there is hissing noice from the front speakers.
Has anyone else encountered this problem or heard about system freezes??

I disconnected the battery cable and fixed it.
Hope it doesnt happen againOther than that Ive been lovin this ride so far

It has happened to a number of us, its a glitch, electronic equipment has it sometimes. It shouldn't happen again (we hope). It happened to me early when I had the car (seems you have to) I now have 17K+ miles on my car and have not experienced it since.

 

Hey, Thanks for the good news.I was so upset when it happened.
Seems to be working great now with my Moto v-600
So glad to find this forum

thanks

 

The similar thing happened on my car twice in past 18 months. The most recent incident was yesterday. I had to stop the car, turned off the engine and my mobile phone, then restarted them.

My dealer prolly would say "cannot duplicate the issue", but anyway I'll have them check in my next visit.

 

This happens to my TL about 3-4 times a week. I have tired of asking my dealer about it.

The next time I go in for an oil chang I'll try to have them put in a neew BT module
