isn't the 6.2" Starlink HU the same HU used in other Subaru models?
If so, those models will experience the same BT connectivity and sound reproduction issues as the BRZ. I don't think you are alone in your plight.
I believe that Clarion makes the Starlink HU [see link -->

so it is Clarion you need to vent frustrations to, although, I guess in the end, it all comes down.back to the Subaru product team and their design specifications for the base head/multimedia unit.
I'm guessing faster would have equaled more expensive; however, on large scale auto production across 100ks/1Ms of vehicles those costs get minimized, but they still add up over time.
The longer Subaru can milk a 2014/2015 design, money can be "saved" and diverted into other areas. One less thing to think about.
of course nowadays, when AA/ACP are so important in vehicle purchases, people skip cars that don't connect or play nice with their phone and the technology, or lack thereof, dictates a purchase and not the overall vehicle function or performance.
I guess manufacturers now need to put more emphasis on the HU functionality/performance than in days pasts.
