If VBOX Touch is struggling to acquire satellite lock, a GPS coldstart may be required. This may be necessary when the unit hasn’t been used for a number of days or has dramatically moved location since its last use.
To perform a coldstart, press the COLDSTART button within the Diagnostics Settings menu.
When the button has been pressed, the unit make an audible sound and a ‘PLEASE WAIT’ message will be displayed on the screen which will count down from 3. The number of satellites will then be displayed as '00' and GPS status will show ‘SEARCHING FOR SATELLITES’ until satellite lock has been acquired. It will take approximately 25 – 30 seconds for the unit to reacquire satellite lock.
