hi everyone.
i am an apprentice electrician and have taken some basic electronics classes, but thats it so keep in mind when responding that i may not know what your talking about if it gets too in depth into the theory.
heres my question:
the car stereo that i have right now allows me to pair my cell phone with it via bluetooth, allowing me to talk through my stereo/car speakers. my goal is to be able to bypass the entire bluetooth operation and somehow wire a sim car reader out of an old cell phone directly into the stereo, allowing me to make phone calls without an actual cell phone being present. by doing this i wouldn't need to keep a charged cell phone in my car anymore because it would all be done within the stereo itself. keep in mind the stereo seen here: **broken link removed** already has the ability to dial the number directly on the faceplate, so all i would need is to implement the sim card.. i think.
i dont know how exactly these sim cards work (the one im working with is from t-mobile) or if it would be possible to make one from scratch. if anyone can lend a hand it would be greatly appreciated. diagrams/circuitry of similar or existing components are welcomed.
thank you.
