1st a question... Has anyone else just downloaded SD2 (from a link somewhere else on this board) and updated only the Bluetooth to 3.11?? BTW, this skips the Z120-BT F/W and BT 3.10 updates.

I had read conflicting info about whether this would work.

Besides hands-free phoning, I really like to play streaming internet and MP3s from the phone over the BT connection. The quality was excellent. So after the update, I tried connecting and playing an MP3. It sounded horrible - like a cheap AM radio. Streaming internet was also distorted - with no fidelity. Like a very low bit-rate compression.

So, back to my question...has anyone else done this? If so, how did it work for you?

I wonder if there is a way to go back of the original BT (ver 2.5, I think)? Maybe the 3.11 update is just a patch of 3.10 and not a full release?

Otherwise, I guess I need to purchase the full update.

Well, maybe I'm the only one to try flashing just the BT update off the downloaded SD image. Anyway, I've been living with this for about 1 week. Yesterday, I was updating the ROM firmaware in my phone (HTC HD2), which wiped out all my pairings - and most everything else.

When I re-paired with the AVIC, I immediately noticed an improvement in the quality of streaming audio and MP3s. Sounded like FM radio again - instead of low quality AM. BTW, I never noticed a degradation of hands-free audio. It was only "phone quality" to begin with. I wonder if the two profiles use a different bit-rate.

Now I don't think the new phone F/W fixed anything - since it was working fine before I updated BT on the AVIC. I also don't know if I did anything different in the pairing procedure than the several attempts at re-pairing last week.

So, I am posting mainly to assure all that updating just the BT to 3.11 off the SDs was possible and had no ill affects. But, frankly, I wouldn't recommend it unless you are having BT problems that you hope to fix with new Parrot software. I really didn't see anything new there - feature wise.

There was an important note in the F/W instructions to do BT update 3.10 prior to doing 3.11....

But if it works.... then kewl!!!
