It helps if you understand how BMW program their cars for various markets

There are many many programmible options in BMWs

When a car is first configured for a specific market, BMW Marketing Dept sits down with the factory and designs a fixed configuration for the market that complies with local regulations and legislation, and also reflects what they believe to be the right mix of options for the price.

They determine a 'fixed configuration' that then gets set in concrete and becomes known as the 'vehicle order'

So when a car is updated with software, it is updated and configured so as to comply with the vehicle order for that country

So, for example, taking your car into consideration: you had changed a few settings using NavCoder that made your car different to the vehicle order for the UK.

The dealer did exactly what BMW expect him to do: he ran the automatic software update utility on his PC, and that checked the vehicle order, and loaded the correct software and settings to the car, applicable to your country and your vehicle order.

The fact that it overwrote some of your changed settings should not be regarded as the dealer doing something wrong.

I have created for you the ability to customise and alter various individual settings with NavCoder - but I cannot override the country specific configuration, because that resides on the BMW PC, not in the car.

So just accept that the dealer does what BMW tell him to do, and then use my NavCoder afterwards to change your custom configuration back to what you prefer.

However, I do accept that they should NOT have overridden your Car and Key Memory (CKM) settings, as these are BMW designed customer options that you can choose for your car.
I believe they should have first read and printed the CKM settings before they changed anything.
Then do a complete car re-program.
And then ensure the CKM was set back to the customer preference.

I would expect that your dealer should reset the CKM back to your preference at no charge, seeing as CKM is a legimate customer customisation capability.

Don't hassle him about what you changed with NavCoder - this is a private customisation that you did independent of the dealer, so don't even discuss it with him - you'll just confuse him and possibly make trouble for yourself.

As for NavCoder having CKM capability - I am continuously looking at what I can add and how - some things are easier than others...
