Does anyone know if it is feasable to add Bluetooth to the Prius after-market? I purchased the AM model because I didn't like the NAV package or the JBL stereo, but I am interested in the phone interface. Any way to get this without adding the entire NAV package? Thanks in advanced.
You could get what you want with a 3rd party nav device such as the TomTom nav w/ bluetooth. Cheaper than factory nav, and probably cheaper to update the nav info.
If you're talking OEM, then no. The NAV ECU handles the bluetooth functions as well. And without NAV/Bluetooth, the microphone, corresponding steering controls and buttons on MFD are not installed.
