Hi Everyone,

I've been on this forum for some while now and used the IDT mods from the first version. I've an f900bt updated with the 3.020200 firmware, but my bluetooth connection wasn't working anymore since i updated my avic to 3.0 some months ago. I'm ably to pair my phone (HTC Diamond) with the F900BT, but I'm not hearing any sound when I've received a phonecall. Also the mic is not working (was working before updating, the mic is not the problem). My radio/navigation sound is stopping when i;m receiving a call, so that's working properly.

I know that it's not my phone because everything was allready working before the 3.0 update.

I already tried everything that I could think of:

1) Reinstalled the 3.0 firmware

2) Updated to 3.02 firmware

3) Installed 3.0 firmware back

4) Reflashed WinCE

5) Removed all User Save/ Setup files

6) Removed User settings via settings panel

7) Restore factory defaults.

UPDATE:

Downgraded to the 2.0 firmware

9) Updated to 2.009 firmware

10) Reinstalled 3.30R3 Bluetooth firmware

But still no succes..>!

Does someone know what I need to do to fix this issue? (I want this to work.. !!)

Please help me.

thanks for the effort,

Galadril

I'm now going to try to downgrade the fimware back to 2.0 (http://avic411.com/forum/viewtopic.php?f=33&t=27155).

Maybe this fixes something....?

Just to let you know, i've reinstalled the 2.0 firmware, but still no succes.

The second step was to update the 2.0 firmware to 2.009, but still no sound or mic...

I'm able to pair my phone, but I don't any sound and my mic is also not working.

Whyle it did until the 3.0 update..

Any ideas??

I found this on this forum:

I was monkeying with the system, and discovered I made a mistake when I hooked-up the front channels to my amp. The RCA's for the front channels were being pushed through the amp where I mistakenly set the amp's crossover to low-pass. Obviously the Bluetooth and navigation sounds weren't going to fall in that range, so they didn't get passed out to the speakers. Once I correctly set the amps' channels to high-pass, everything started working just fine.

Can this solve my porblem?

I've downgraded to 2.0, then updated to 2.009 and now i'm back on 3.02.

My girl's phone is working, but mine still not. I think this is a problem related to windows mobile 6.5.5...

Does someone know the awnser for this?

I noticed on my unit, sometime at high speeds, somehow my "phone voice volume" gets turned down automatically. I was thinking that my bluetooth wasn't working, but all I had to do was turn the phone volume back up in the phone settings. Hope that helps.
