RCD 510 Premium Bluetooth HTC Touch Pro II (Rhodium) problem

[manowar]

Hello everyone,
I'm having a problem with the RCD 510 Premium Bluetooth kit that has been troubling me for over 2 months now.
When I first got my Scirocco the Bluetooth connection was working fine (for 3-4 months). One day out of a sudden the Touch Pro II was not pairing anymore with the car's bluetooth kit.
At the time I was using Windows Mobile 6.1 that originally came along with the phone. I tried the basics - deleting the connection, re-pairing - with no success.
So I gave a shot at phone's factory reset - still no luck. The phone is recognized when I use the "Device Search" function on the car, it prompts me to enter the pass code provided, I do so, the phone loses the GSM signal (which of course is normal) but then suddenly I get a message on the RCD510's main screen "No bluetooth connection to phone" that lasts for about 2 seconds, and then a message on the Multi Function Display of the car that says "Pairing failed".

Since the problem began, I tried factory reset the phone (as I mentioned before), and tried pairing before installing even a single software, still no luck.
I tried multiple ROM's in the meanwhile (I mean third-party ROMs from xda-developes) and now I am using the official Windows Mobile 6.5 from HTC for my phone.
I also did many tests using third-party applications for the rSAP protocol (JetWare hands-free extension, SAPSettings, some patched found around the net here and there) even though there is native support for rSAP since the first firmware that came along with the device.

Please note that this phone uses the Widcomm Bluetooth Stack - not the Microsoft one.


Any help/ideas would be greatly appreciated.

PS: I apologize for the big length of the post, but I believe the more the information I provide, the more the chances to get proper help

Hi Manowar

I'm sorry I can't help but have you spoken to your dealer on this issue?!

Actually no, because I have tried other phones (Nokia, HTC phones with Windows Mobile 6.1 & Microsoft Bluetooth Stack) and they work fine.

99% is a phone problem, but I posted on a car forum hoping that another RCD510/Scricco owner might have stumbled into this problem and managed to find a solution.
Also I believe that the dealer most probably will response that the phone is not compatible, and I will argue that the first 3-4 months everything was ok, and we will keep arguing...etc etc You know how these things go....


Thanks for your thoughts though.

Anybody else that might be able to shed some light at the end of the tunnel?

Some more information regarding the whole subject:

I found out that when I press the "Emergency Call" option on the touch screen of the RCD510 (i.e. try to call the international emergency number - 112) and then immediately end that emergency call, the next time I try to pair the Touch Pro 2, it does pair!!! But it has no signal at all, and if you try to make a call you get a "Dial up error" (or something like that, can't remember exactly)!


Any ideas what could be the reason for that, or how it could be relevant with the whole problem?


Thanks.

Some more info for those who are willing to give an opinion:
I did eventually decided to remove the car's battery. I left the car without battery for approximately 40 minutes. Now here's the strange part: All the settings of the card indeed reset (window settings, light settings, etc) BUT the RCD510 was not affected at all by the battery removal! Yes, as weird as it might sound, the station list was there, bass/tremble customizations were there also, everything in place (regarding the radio unit always).

Side note for all those who might remove the battery from a similar VW car:
As soon as I plugged the battery back on, I had somewhere 15+ warning indicators on my dashboard turned on. From ABS malfunctions, air pressure, EPS malfunctions etc. But after rolling the car for 3m or so everything turned off. Back to normal. Probably had something to do with the electronic sensors giving proper signal to the car's "brain". Just my opinion.

Now, besides that - the fact that removing the battery didn't perform a reset of the radio (RCD510) unit, I also tried reverting my Touch Pro II to a WM 6.1 cooked ROM - don't remember which one exactly - but that didn't helped either. Same stupid error message after pairing for 2 secs: "No bluetooth connection to mobile phone".
And to confirm again: My X7500 (Athena) with a cooked WM6.1 ROM from michy still pairs and works fine. (Tested it last night, just to make sure that battery removal didn't had any side-effects)

PLEASE help me if you can. Any suggestion/recommendation will be greatly appreciated.

PS: I decided to contact the car's dealership to inform them about the whole problem. I will post soon regarding how that went...

Thanks for your time everyone...

By the way, does anyone knows the proper way to reset the RCD 510 to it's factory default settings? Besides the function that is given inside the menu itself - I already tried that. I was just wondering if there was a "hidden" way that will entirely wipe all settings/customizations from the unit....

[manowar]

After having a conversation with the dealership, they said that they cannot help me since the TP2 in not included in VW's list with compatible phones (didn't expect nothing more to be honest).

The guy that I talked to recommended that I removed the battery once again and leave it a bit longer.

Did that yesterday: Left the car without a battery for almost 2 days. The STUPID RCD510 did not reset! There must be an internal battery or something!

I know I have asked this before, but does anyone knows a way to HARD reset the RCD510? Besides the "Factory Reset" option in the menu - that one only resets the radio part - bluetooth settings and profiles are left intact.
Or even better - a firmware upgrade. For the RCD though, not the RNS.

As weird as this may sound, I did manage to find the "source" of the problem (but unfortunately not the reason nor the solution). I came to the conclusion that my Touch Pro2 does not connect with the unit when I am using the SIM card of my specific GSM provider. When I use a SIM from any other provider everything works ok. And also when I use the SIM of this specific provider in any other RSAP compatible phone it works ok. So in a nutshell: Touch Pro2 + MTN (in Cyprus at least) = failure. Hope this saves someone some time.

Thank you everyone for trying to help.

How old was your SIM card?

I have had problems where simply updating the SIM card did the trick (I know....weird!) - You can usually ask your provider to give yo a new SIM card, even if you have to damage it to justify it, could be free but probably a few quid.
