SAP-Support doesn't work

---

Hi,

I have a HTC p3600 and want to connect it to my Mercedes Bluetooth-cradle.
Before I bought the phone I thought it is no problem, because it has SAP-Support. Now I had to see that it is a problem. The cradle doesn't find my phone!!!! Does anybody have an idea why it doesn't work???
Some registry-entries?? A wrong phone-name?? A general problem???

I'm sure that you already checked all the settings on you bluetooth like "make discoverable" etc.?

yes.
But is the name important?
Mybe there is something that I have not checked, but I don't know what's important.

Have you used the Mercedes BT successfully with another device? Have you forced the phone to look for other BT devices?

I was at mercedes to check the cradle before i'll buy it. I hadn't to much time to check everything.

Have you forced the phone to look for other BT devices?

no, the mercedes-guy told me that I will not find the cradle. I used the internal bluetooth of the car to test if my mobile is visible (it is).
I have read some other posts (of another device) where the car doesn't find the phone because it is a PDA and no mobile. Is it possible for this device also?

Is there anybody who is using SAP successfull with the trinity?

EDIT:
Now I have tried this:
http://forum.xda-developers.com/arch.../t-274226.html
but I can't edit my registry. It always says "Zugriff verweigert" (in English: "Access denied").
Now I have tried another registry-editor. It allows changing the value, but after a softreset the old values are back again.
