The reg edit is to get the nav audio through your existing visor kit, if you get an iO-Play module you won't need to do this.
As for getting two devices connected at the same time one has to use HFP (Hands Free Protocol) the other uses the A2DP Stereo Audio over Bluetooth Protocol) you need to be careful when setting up the pairing(s) between the devices, but you should be able to get two phones working this way, pair the m700 to use the A2DP and the newer HTC TC2 to use the HFP connection.
When pairing the devices pair the first one then turn OFF the bluetooth on th edevice before trying to pair the second device, if you have one device connected with the Bluetooth still enabled the iO-Play will not spot the second device, had I known this when I set mine up it would have saved a few hours of frustration! - Mike |
