Disable voice-activated dialing from Q10 to bluetooth car speaker

I just paired my Q10 successfully to my Motorola Sonic Rider TX550 bluetooth speaker in my car. It's awesome. However, when setting it up, it asked me to turn on voice-activated dialing, but I didn't realize that it would download my contact list to the speaker and not allow me to dial a number that's not in my contacts. I've looked on the Motorola support pages and can't find anything re: how to change this, so I'm wondering if someone could point me in the direction of how to disable bluetooth voice-activated dialing from contacts on the phone itself.

Thanks.

Delete and repair, and say no this time,
