Hi guys,
I have searched up and down this forum and other forums, some problems get close but none of them hits the spot.
I am using an HTC Touch with Windows Mobile 6 Professional, Version: CE OS 5.2.1238 (Build 17745.0.2.3) and link it via Bluetooth with the car navigation system Becker Cascade 7944.
The link is established but calls are muted. Becker had this problem with some other phone models too and brought out an update version 3.7.
Now the calls are not muted anymore, but the sound is distorted. It sounds like the loudspeaker is broken. In short: not usable.
I posted this problem with Becker and after the update version 3.7 they sent me this mail (translated from German):
Dear xxxxxxxxx,
the System-Software 3.7 was sent to a lot of customers as update. Only
positive results came from this and we did receive no negative replies or
complaints except for two models from HTC.
Please contact the manufacturer of the mobile device and ask for a
possible software update.
We regret we can’t give you any other answer.
Sincerely
i. A. Martin xxxxxx

Then I sent a fax to HTC Europe headquarters asking them for support and /or a solution. Nothing heard from them.
I then sent a fax with the HTC Europe headquarters fax attached to the Chairman of HTC (see www.htc.com) in Taiwan. Same result, no reply!
In the french forum www.planete-htc.com they have a post that the CAB-file WM6_BT_DUN.cab could solve the problem. I have not installed this file yet, since I don't know what it does or if it solves the problem.
Could it be that HTC uses a different bluetooth stack or CODEC-files?
Can anyone help me?
Thanks a lot

Hi!
I've got the same problem with an other phone from HTC (MDA Vario 3 from T-Mobile) and my Becker Cascade. Spoke with Becker, no solution in sight. They said I've to talk with the producer of my mobile ..... grrr.
Bye the way, if you make a call and after being connected with the other side you can press "private" in the options menu to give the call back to the phone. Then again press "private" in the options menu and you have a clear connection without distortion!
Bye, Peter (Germany)
PS: Tried the CAB-file, no change
hi @ all I have the same problem with a becker Casscade pro and Firmware 3.61 and - now - 3.70.
This problems is only with HTC devices that have installed Windows mobile 6, (Wings, Kaiser, Touch..) with the older ones like T-Mobile Vario and Windows Mobile 5 it works fine.
by the way the same problem, the other side hear no sound from you, and you hear the other scrambled
and it is not depend to use Sim access profile or normal earphone profile.
maybe i think, the Becker car radios are not longer supported from the manufactur..
the right way is, to change the bluetooth stack on the HTC devices. there are some parameters between mobile and bluetooth called EHR
and this parameters are wrong. maybe by HTC configuration or Becker
A Nokia E61i and many other WM5 devices works well with Becker casscade pro.
i can try tomorrrow some AT&T Models with windows mobile 6 (Samsung and some other) maybe they works...
soon, now i test a becker casscade with a samsung shg 6xx smartphone with WM6.
BT Profile works very well with casscade 3.70 firmware.
so it´s a problem of all actually HTC devices with WM6 i think.
maybe we should change the BT Stack was inatlled as default...

Hi joy.d,
I thought of the same solution.
I tried one of ROM cooking guys in this forum about how to change the BT software, but no reply.
Do you know how to change the BT stack on the HTC?
By the way I am using the HTC with the Jabra BT320s and the Plantronics Discovery 640X. Both work well.
And the Cascade worked and works with all other phones I know of. There is a forum in Germany for the Cascade and they report only problems with the HTC.
Also, some in this forum have reported BT problems with the HTC Touch.
So, please let me know if the BT software upgrade/change works.
Take care

hmm.. i have no time to cook my own rom with fixed bluetooth drivers. (maybe the actually bt version from broadcom, better knows as widcomm stack works well) we think in our company to change from htc to other manufactor, the bt problems not the only one problems ;-)
but if i found somethink i will tell you please let me know if you find something.
p.s. the BT update for htc kaiser dont change or helps.
maybe becker has a problem with her integration of bluetooth.. with the most bluetooth headsets works the htc devices. (i test over 20 different BT Headsets with HTC devices, but the most with WM5)
Same problems
I have the same problems. HTC Mobile 6 with Becker Cascade. To work around this issue, press [Private] in the [Options]Menu, once in a call, and then return back following the same keysequence.
According to the User Manual, Becker only supports the bluetooth HFP1.0 profile...
Hmm, and the Windows Mobile 6 Devices supports:
A2DP (Advanced Audio Distribution Profile)
HFP1.0 (Hands-Free Profile)
HSP (Headset Profile)
It´s work with a Samsung blackjack, so i think the Problem is by the provided BT Stack from HTC..
Headset profile
When the connection to the phone is made, a headset icon appears in the upper homescreen. It seems that the headsetprofile is initially used. When you execute the private workaround, the phone switches to handsfree...
hmm, i tried it with this private funktion, but the quality of sound is not really good or better. is not a really funtional workaround. I have test the Becker cascade now with an Asus P750 Phone, and it works well too..
i think it is a HTC Problem.
Cascade Pro + HTC Kaiser
Hi Guys
I am experiencing exactly the same problem with my HTC Kaiser and Becker Cascade Pro 7941. It really makes you upset when no one helps you, becker says its handset manufacturer's fault and HTC dont even bother to reply.
yes, that´s sad. if you found a solutions let it know us, in germany, there are some more users with exactly same problem. :-(

Hi... not 100% related, but I have an HTC VOX and that works fine with the Becker High Speed Pro 7945 (same software as the Cascade) which I recently flashed to v3.6. The Becker works fine with 2 other HTC phones that I have, SP5 and SDA. The only difference is that the VOX actually displays the signal strength bars on the Becker bottom RH corner...
NOT all roses I am afraid as since I flashed my Becker, I lost ALL navigation functions..... but all other functions including the phone still work...
hi fwd, but your Fox and the other devices is running with Windows mobile 5, right?
With WM5 all devices from HTC works fine with becker

Hmm... sad..

Yes joy.d, the VOX is the HTC S710... sorry should have mentioned that earlier - it is easier just to refer to it as the VOX

fwd (aka snippi)
i found a video out cable and it clearly says that works with:
HTC Tilt 2, Pure, Fuze, Touch Pro2 (Verizon), Touch Pro (Verizon), Touch Pro2 (Sprint), Touch Pro (Sprint), Touch Pro2 (US Cellular), Touch Pro (US Cellular), Snap (Sprint), Touch Pro (Alltel), Touch Pro2, Touch Diamond2, Touch Pro, Touch Pro2 (T-Mobile), Verizon Ozone / T-Mobile Dash 3G!
And i ask you,is it possible?
I'm just guessing, but even if it did work. It would be just as slow as remote desktop app like Pocket Controller Pro. Sorry to be a pessimist
Hi all,
Recently got my company car, a Prius, with the Toyota Touch pro nav system in it. This requires Bluetooth DUN support so I will get updates and search, etc.
Unfortunately, I understand from the specs of my HTC Trophy the DUN profile is not supported. My carrier does support Internet tethering, but that is only offered on my phone via WIFI. I would not mind to install a custom ROM or some additional drivers/apps to enable this. Any suggestions or other people with this problem?
And yes, I know, Bluetooth DUN is quite old, but unfortunately, it seems the car industry lags far behind the technological evolution if it comes to there nav systems. I mean; why not just add an iPad dock ?
Thanks all; great site this!
