Just another note! I was amused at the invoice line item for the NAV system firmware update. It read "Firmware Update for Navigation Update", the next line read "Cause: Poor Programming" and the line after was "EL9014 Navigation OS Update". The service tech mentioned system speed and Bluetooth problems as reasons for the update.
How to check to see if I need the firmware update? I have been having minor Bluetooth issues. Thanks!
