ProDrive Sat Nav system

Hi

Im new here and have only just passed my cat c, I decided to get the prodrive satnav to use. Any suggestions is this a good buy■■? does anyone have any idea how to update as I have tried and the website is asking for a username etc, also I cannot seem to access the bluetooth menu, i have literally just switched it on so do I need to run a setup first or is it reliant on GPS connection to allow access ■■? Any info would be great.

Thanks
