Hidden "Service" Test Menu

There is an inbuilt menu in the Connect Nav+ unit that allows the user to ensure various modules are working, and that the speakers, antennas and GPS/GSM systems are functioning normally. To access this menu, do the following continuously and quickly:

Press "Setup".

Press a "Connect" softkey (i.e. push either button 10, 11 or 12 of the 12 buttons along the bottom of the screen).

Within a second, press a "Connect" softkey (same as above) 3 times repeatedly.

Press "Enter".

Scroll down to the newly appeared button "Service", and press "Enter".

Turning Screen Off Whilst CN+ Is In Use

Simply push and hold down "Main" for about 5 seconds. Press any function button (e.g. main, nav, audio, tel, map) to turn it instantly back on."
