I have the OTTOCAST U2-AIR Wireless CarPlay bought in October 2022 and its still flawless in my 2017 Sport.   There's later models of this brand and expect they'd be just as reliable and possible additional features.

I would also like to find a good wireless carplay adapter.

Its on top of the engine, kinda just behind the oil dipstick & oil fill cap. Between the engine & the firewall.  Pre 2019 2.0's are under the engine between the engine & the splash guard. 

took off from stop sign in heavy traffic, all of a sudden i hear a hiss of air and immediately think i just blew a tire, not the case, as i continue i hear a whoosing of air from in front of the passenger side as i am accelerating. once i hit high gear it stops, but if i apply the gas it begins again until i let up and car is no longer accelerating. investigating i am drawn to the conclusion that it is the blow off valve.   any thoughts, if it is bov where is it located on 2019 edge?

Yah I talked to a shop today and they estimated about that so I will just let the pros do it after all since AC seems a bit more than I want to get involved in. Good point on the possibility of package policy coverage.

I never understood swapping out a BOV/DV unless it's leaking or can't hold the boost it's seeing etc. 

ls7t-19c107-xc from Ford Fusion and is designed for the Sony amplifier. Unfortunately, it does not fit the Bang & Olufsen amplifier. I am waiting for the KT4T-19C107-DE to be delivered.

I'll check for the Sirius update.  Odd that that would happen after driving for about 20 minutes, shutting it off to run into the stop and go for less than a minute, then get it, start the vehicle and have no back up camera or stereo for about a mile, can't even use the power button to get it to come on.  Dealer called me after I emailed them for I felt is a lack of trying to solve the problem.  They are getting me a loaner lined up and they're also going to replace missing splash shield bolts since they do all me oil changes, had to bring that up to them also, like I wasn't going to check their work.
