I'm a Subaru tech in Australia, there has been at least 2 firmware updates for your unit since the unit was built. Compared to the current Harman units this article is about, your Fujitsu unit is basically a saint. But some of them do have problems, like with anything mass produced. Try more than one dealer if you can, sometimes one dealer may not be clued up on latest updates, others are right onto it.
