I do not have the 8" Nav - I have something like 6" or so - so I cannot download software as mentioned in other messages. I saw a note to hold the volume button for 10 seconds and that worked for a day or two. I emailed to Subaru Customer Services ([email protected]) about this and got a rapid reply.
I hope that is very soon. And I hope this helps some other people."We are aware of some operational concerns. There is currently no software update available, but our engineers are working on one for the 2019 models. As soon as the update is available we will let you know."
