Am running Cm7.1. I have about 2,000 contacts. My Nexus One and Pioneer headunit insist on exchanging all 2,000 contacts if my Android Contacts "Display Options" are set to "My Contacts." Problem is that this really makes Voice Recognition unusable (too many contacts to parse).
To get around this, I created a "Car" label in Gmail for the 21 contacts I want. If I change the "Display Options" to just "Car," only the 21 contacts are synced and VR works great. Problem is that when not in the car, I would like "My Contacts" to visible on my phone.
I would like to sync only the "Car" label, or only sync manually. I can't figure out a way to control this.
