I'm pretty sure I've got this right. I've tested this a couple of times now.

On the V710, you have the capability to do "speaker independant" Voice Dialing (similar to the TL's Navi Voice Recognition, but maybe better) and the V710 also has a Speakerphone capability.

But not when the Bluetooth Audio Gateway has been opened with the 04TL. For some reason, you can't make a Bluetooth connection with the TL if you are using the V710's speakerphone capability (say, before you get in the car). Also, as mentioned above, you can't use the V710's "Name Dial" or speakerphone once the the V710 has established a Bluetooth link to the TL.

This doesn't seem to be a hardware related issue. You can use the V710 as a normal cell phone after it has linked with the TL, so the V710's earpiece and mic are not disabled after the Bluetooth link.

It just seems odd.
