Wythie Posted October 23, 2015 Share Posted October 23, 2015 For some reason I cannot access many functions on the 840 which I couLd previously access. The sat nav and audio stuff is working but when in settings most of the menU is grayed out. The only thing I can think of is that I started the car with the security panel on the 840 removed! Should cause a problem? Quote Link to comment Share on other sites More sharing options...
Dogconker Posted October 23, 2015 Share Posted October 23, 2015 Sorry, I can't help you with this, I did't have the inbuilt satnav. The only thing I can suggest is a reset, I imagine theres an option in the manual or contact the dealers. sorry that's not a lot of help Quote Link to comment Share on other sites More sharing options...
bitman Posted October 23, 2015 Share Posted October 23, 2015 there is a small hole with a switch to reset the unit by using a paperclip or... may be you handbrake wire is loose making the unit thinking that you are driving? Quote Link to comment Share on other sites More sharing options...
