I have now managed to stream audio to the car head unit via bluetooth. I've tried using WMP and TCPMP and both seem to work ok. The sound quality is unbelievable and all functions are controllable from the stereo.
The trouble starts when I try to use the phone for streaming audio and making/receiving calls at the same time.
To make a call whilst listening to streaming audio, you must change the mode on the head unit from BT Audio to Telephone. This mutes the audio (but doesn’t pause it as I think it should) and allows you to either voice dial a number or select a contact from the memory on the stereo. The call is made successfully but when I hang up and the head unit automatically switches back to BT Audio, the audio crashes and sounds like a CD that is stuck. Exactly the same happens when an incoming call is ended.
Also, while streaming the audio to the head unit and then temporarily changing the mode to Tuner to listen to the radio, the pairing sometimes disappears and the phone starts to play the audio through its own internal speaker.
I think the problem is that I am using the same device for the handsfree and the streaming audio and that maybe the M600 is a bit slow for this. Maybe overclocking the device might help? Anyone agree?
As far as the hands free element of the stereo is concerned, when not using it in conjunction with the streaming audio function, it works very well. There are however a few bugs as follows…….
The phone pairs with the stereo ok the first time but from then on, the automatic connect feature does not seem to work with the M600.
The only way to get it to connect is to dial a number. It then takes about 15 seconds before connecting.
The way I have overcome this is using PocketZenPhone which I already have installed. I have created a profile on it called “Car” which, when selected, rotates the screen to landscape mode, switches the volume to maximum, turns on Bluetooth and now I have set it to dial 150, the orange customer services number.
The reason I make it rotate to landscape is because I have TomTom installed and I prefer it when in landscape mode. Incidentally, TomTom seems to work fine in conjunction with the handsfree function.
After 15 seconds, the phone connects and I here the orange lady nice and loud through my car speakers. It serves as a pretty good test that the devices are connected and it doesn’t eat in to my free minutes.
Transferring my phone book to the stereo memory was extremely annoying. You have to do this using Bluetooth and on the M600 you can only send one contact at a time. I read somewhere that Pocket Informant was able to send multiple contacts so I downloaded the trial version of this to the phone. After selecting all 92 of my contacts and initiating them to transfer, it got to 28 and froze. From then on it wouldn’t do more than 3 at a time, then for some reason when I opened the newly transferred phone book on the stereo, there were some contacts missing and lots of duplicates.
I’m still unsure as to the benefits of transferring the phone book to the stereo, especially if like me you have the phone so that you can view it easily from a driving position. The method of finding a contact in the stereo memory is quite clumsy and involves about 7 or 8 glances at the stereo if you have more than one number for one contact. Voice dialing however works extremely well, better than I expected. You press the telephone button, then press and hold the band button to initiate voice dialing. I have about 15 of my most regular contacts stored as voice tags and so far it has recognized each one correctly without exception. I think I’ll record more of the voice tags when I get time.
