So I'm doing a custom Bluetooth setup with the stereo in my car, and everything works great except for the fact that I can't activate Siri using any of the buttons on my stereo. What I need is an external home button that I could press to activate Siri quickly, sort of like those "shutter" buttons (that really just replicate the volume button being pressed, I believe). I have found *one* Bluetooth external home button, but ideally I would like to have one that could connect via a 3.5mm jack (complicated, but this would work better for me). The only "External" home button I found that connects this way via 3.5mm is sold in a car kit that I do not need, and is sold-out by the company anyway. I haven't heard a response from them, so I figured I'd look elsewhere. If anyone can help me out, I need a button that will replicate the home button being pressed, that connects via 3.5mm jack. Thank you!
