"No Antenna" Message

A few times now when trying to listen to satellite or use the navigation it says "no antenna". The satellite stations dont come in and the nav doesnt work correctly. After either a few minutes, a few hours or once even overnight the antenna will come back online and everything works fine. It sucks trying to take things back to the dealer for intermittent faults like that because they dont ever seem to occur once the car is there (go figure).

So I was wondering if anyone else has experienced this? And if you have, did you come up with solution? Thanks.

It's your head unit. What does your VCDS scan show?

You within the basic warranty? I still think it's the head unit.

I think the sharkfin antenna is only for the SAT radio, and the GPS antenna is in the dash.

Youre probably right considering there are two different antennas. It seems to be intermittent for now but I wont take it to the dealer until it totally stops working. Im covered under factory warranty for another 20k miles.

Car having same issue. Works for a few hours and then “no antenna”. Checked antenna plug which was fine. Car out of warranty. Am I going to have to replace radio??

Personally, I'd start with a new antenna.
