The first time he was in the car. Said he never saw it before. The second time I was just sitting in the car getting familiar with the head unit functions. Salesman said he couldn't report it to Subaru until I bought the car. I don't plan to buy that one! Just wondering if it was a wide spread problem.
I took delivery of a 2018 Touring Thursday that has that HU.
I've not seen that happen yet.
What I do see regularly is a modal dialog box saying "Signal not found" (I forget the exact wording) and I think that refers to the Sirius satellite radio. It goes away after a few seconds, generally, but it DEMANDS your attention and gets in your way, for something that's pretty much never vital for your current purpose.
I griped at the dealership about that yesterday, told them the people that chose to do that should be shot. Seriously, for a car that's otherwise bending over backwards for safety equipment and trying to not have a distracted driver, how could THAT get past their thinking? I guess they were testing where they always had solid signal quality. Sirius seems to be fragile to a lot of things, including trees, when it comes to signal reliability. What makes me mad about it is it pops up, even when I'm not even trying to use Sirius. At least, I think it's Sirius it's reporting: it doesn't identify which signal!
I wonder if that part of the HU code is open source, and if I can get things built and installed after modifying it according to a sane way of doing things... my fear is the system may require it be cryptographically-signed by Subaru or whomever makes the HU, and won't be possible to modify what's there, short of getting their private key (that'd be a real problem for them were that to happen!).
