hi all;



I´m with a big problem in my 530d E39,I tried to upgrade the navigation software but something ran really badly.

I have a MK III navigation drive with V16 software on a 16:9 display , I tried to install the V31 software in order to update my system , everything ran fine till the end,but when the system reboot said this: "insert key CD or system 17".
now the display only shows this ,all the other functions works fine but the display shows this message all the time.
I think I need a key CD for this V31 version, I think this is because I had V17 prior version,I tried to search on the internet for this key but apears to be impossible to find it.

I´m very sad about this because I tried to improve my system with a new firmware,but instead I messed up.

I was on the bmw local dealer and they told me they don´t have any software discs to sell,only navigation cd maps.

I removed the GPS drive from the trunk to see if there is any reset button but I didn´t found it.
at the same time I tried to leave the drive disconnected from the car for about 2 hours to see if reset for it self,but once again didn´t result.

I know my gps MK III it´s good,but I can´t solve this situation,I don´t have any key to unlock the system,I think I have to buy a new gps drive,but they are very expensive.

I ask for someone to help me, I don´t know what to do, put this drive on the trash ,and buy a new one , or try to unlock this,but how can I do it?

any help please?

thanks very much,and sorry for my english.

regards
