The CPT8000 works fine, both as a handheld, and when connected to the car. All of the "in-car" phone features operate as advertised and/or explained in the manual. However, I have two issues:

1) When docked in the cradle with the coil cord attached, when the car is turned off, the phone does not turn off. That is, the phone remains powered on even then the car is turned off. The manual says that the phone will go into standby (i.e. turn off) when the ignition is turned off to preserve the car's batter, but this is not happening.

2) Once a day, immediately after starting the car, the phone dials BMW Assist as if I had initiated an Emergency call by selecting on the car's menu (even though I haven't). This does not happen every time that I start the car, but in the three days that I have had the kit installed, it has happened once each day, always in the afternoon, and it happens just as I start the engine.

Number "2" above is the main issue for me, as I have no way to keep the car/CPT8000 from dialing BMW Assist once a day. According to BMW Assist, they do receive the sent data correctly, and are able to tell my location, etc. So, the BMW Assist call seems to be transmitting fine - it's just that the car is calling BMW Assist without me requesting it.

Notes: After installing the complete CPT8000 install kit, I checked the "Telematics" setup menu of the car. Here I found that the VIN number was empty (filled with seven underscore "_" characters), the license plate entry was blank, the car color was not selected, car type was set to "E38", both phone numbers are set to German numbers (i.e. begin with "+49"), and the last entry, "Aut. Em-call" was set to "No". Note that at this point, the phone was not actually attached to the coil cord (i.e. the entire install kit was installed, including the TCU, but the phone itself was not yet connected).
I changed the settings in the "Telematics" setup menu to the following: entered the last seven digits of my VIN into the "VIN" section, entered the license plate number, the car's color, changed the car type to "E39" (which is correct for a 5-series), and changed the "Aut. Em-call" to "Yes". I did not change either of the phone numbers. [Note that it is not clear to me whether the CPT8000 TCU actually uses these values, or ignores them entirely.]

I have talked to another user who has a 2000 528i and self-installed his CPT8000 kit. When he entered the "Telematics" settings, the last seven digits of his VIN number were already in place (i.e. it had automatically been transfered to the TCU). In addition, the "Aut. Em-call" is set to "Yes", and he is not able to access that setting to change it. The other settings were just as I found them originally.

After the second day of the car "automatically" calling BMW Assist for no reason, I changed the setting in the "Telematics" menu, "Aut. Em-call" to "No". Regardless, the car still called BMW Assist the next day.

Although the car has, for three days, called BMW Assist once per day, and always in the afternoon, I have no proof that this is time-dependant, or really will only happen once per day. That is, it may be a totally random occurance, that has just happened to have occured once a day, so far.

How can I stop the car/CPT8000 from calling BMW Assist every day?

Thanks for your help,
