This is the route I'm going. If you don't trust them, I won't blame you, but the quality has gone up dramatically since their introduction into the market few/several years ago.
They are basically tethered to your cell phone (BT and/or wired depending on the model you get) for phone, music, internet, you can attach cameras, have a connection to your car's OBDII port for (telematics) engine information................ I even saw an accessory for HD tv........ I honestly think this is the future of aftermarket radios. Few people care about high quality audio. I don't, as long as it "sounds good" I could care less about high fidelity. Having that said, I think there's software (app) you can download or attach to the unit to get high fidelity sound. Best of all, they won't break the bank.
