If that's the case, here's an APK for the app. I couldn't get the one in the PlayStore to install for some reason, but you can try first.

We get sound from the rear speakers in the Cayman, which has non-Bose and Erisin. There is little to no control as such over the rear-speaker sound, but it is there. In a small car with only two seats, we don't consider sound from the rear as important, but others might.

For Bose, it is worth repeating that, prior to removing the PCM, it is recommended to set the PCM to 75% max volume, all faders to their central positions, bass and treble to neutral and the 'surround' mode disabled. The pseudo-surround source is a synthetic form of 'surround sound' - the BOSE amp doesn't have 5 discrete channels AFAIK, so it attempts to create a form of surround sound by phase manipulation of 2 channel sound. Aside from generally sounding awful, if this mode is left enabled, it could have undesirable effects on the sound one hears from an aftermarket unit since the Bose amp may get 'confused' by the signal it is now receiving.

Thanx for the reply, I have the Erisin unit enroute but think I would prefer the larger screen of the CHSTEK. Ahhhhrgg analysis paralysis.

My wife actually prefers the Erisin because the screen is a bit smaller! There isn't a massive advantage to a slightly larger screen unless it is a widescreen, where the two 'halves' of the screen can be used for two different purposes. When the extra screen real estate is vertical, there isn't all that much advantage IMO. But a big screen can look better to some, and that is sufficient reason to want one. If the Erisin is on its way, you could install it and see how you feel about it. If you decide you prefer the larger screen of the CHSTEK, then you should be able to return the Erisin or swap it out. Personally, I like both units more or less equally, and functionally they are virtually identical.

So torn, I spent the last 45 minutes going back in this thread looking for a post where someone mentioned a CSTEK seller who would pre wire the MOST fiber box and applicable SW update as part of the package. Does anyone have that link handy? Or a link to the correct unit for a 981 with Bose. Want to check current pricing to decide.
TIA

I have a 2014 Cayman S with Bose and I have sound coming from the rear speakers with the CHSTEK unit.

I ordered the 7862E plus MOST box together from CHSTEK Official store. They came prewired together.

As mentioned the 7862-E or 7862-D are the ones to go for depending on how much storage you need, although there's such a small difference in price you might as well get the E model IMHO.
