Just wanted to resurrect this thread in case someone comes across it in the future and finds it useful…..
I’ve had the connection woes as described, Google pixel 7a in T6.1
Recently got this cable

Android auto has since been working no problem, including on several long journeys.
Although…. Get in the van this morning and will it connect!? No it bloody won’t. Phone charges but otherwise will not connect and start AA.
Was just about to hit buy on a wireless dongle, but thought why not try a restart of the phone and hey presto, everything working fine again. Bloody technology.
I think the key thing is the data transfer rate, but anyway, can confirm this cable supports rapid charging and AA (for now) in a VW van. Or my van at least…. Maybe it won’t work in yours (disclaimer)
