I unfortunately own a new spy mobile. I’ve done what I can to forbid it from doing things.
One of the more annoying things is they got rid of the Aux jack for the stereo. With it, I could simply plug my phone’s headphone output to the stereo, control what’s playing from the phone, and the stereo would simply mindlessly play what it’s being fed.
Instead, if I want my music on the car, I need to use bluetooth or android auto or apple play (the last being moot for me, I have an android spyphone for now).
Fortunately (?) my cellphone provider made my prior phone obsolete, forcing me to buy a new Android Spyphone (I bought the cheapest one), so I could basically reset and lobotomize the old phone. It has no sim card, so I removed every app that has nothing to do with playing music (that it would let me uninstall), then loading my music library onto it. It’s rather like a retro iPod at that point. I bluetoothed that to the car.
I still want to snip the wires to the antenna, and will once the warranty runs out. Also the in-cabin microphone needs a kill switch.
