Connection difficulties with Lumia 800 and CK 100

Question

I have a Nokia Lumia 800 and an installed CK-100 car kit, the kit has been professionally installed and works as it should do ie it is switched on with the car ignition and can be paired with both my Lumia and my partners Samsung via bluetooth.
The problem I am having is the car kit keeps connecting with the phone resulting in two beeps through the speakers as it confirms it has connected both the phone and player function.  This repeats every 1 minute and is very frustrating.  It does this almost non stop although some times after about 10 -15 connects it suddenly disconnects.
I have found a way to stop this happening, but it is not ideal and certainly not how a hands free kit should be, as follows;
Set the Lock function to its max setting (5 minutes) and tile to the Bluetooth screen, then by constantly touching the screen every 5 mins to keep the Bluetooth settings screen open it works.
I have sent two emails to the Nokia help centre (both times it is clear that they do not understand the questions) and have phoned the help desk twice, on one of the occasions the help desk person told me to reset the phone (which clears all your setting, Apps etc) and it worked fine for 4 days then started as above.
Anybody got any ideas? to me it looks like the bluetooth setting is doing something when it is in sleep mode.

Check whether you may have use your Lumia 800 on another PC initially so it has it's primary sync relationship with that PC.
When you connect your Lumia with your PC and Zune starts select 'phone' and verify the sync relationship which is shown below the phone image. If this says 'guest' you will have to click 'Change Sync Relationship' to move it to the PC you are using.
On any other PC you can remove the phone from the list of know devices through Settings>phone>sync options and click 'forget this phone for each phone you wish to remove. If multiple phone are known to this install of Zune you will see left and right arrows besides the phone image with which you can select the phone to change settings for.
