This sounds like a fuse or power problem
The voice recognition module and telephone control module are separate components. However, they are both not working; therefore it seems like a general issues rather than a single module. I would double-check the fuses. Replace them anyway, even if they look good. If the fuses are OK, it could be a bad car battery or a bad ignition switch.
Re: This sounds like a fuse or power problem
Do you know where the voice module is located? Thank you for the advice..
On the front of the CD changer bracket
