I have seven seater C4 Grand Picasso Feel Blue HDI 1560cc CO2 (B) on a 66 plate. Recently started to have the same issue with my sat nav screen & stereo, which are related to an old THREAD. ![]()
I have read the previous comments & looking for more help/advise. In two minds either to change a new battery or change the SATVAN panel with stereo!! Mine is nearly 6 years old as it was first registered in JAN/FEB 2017 so six years old battery. ![]()
No warnings signs at all or engine stopping as yet. But the mobile phone cuts off too once the sat nav goes BLANK. Citroen main dealer wanted a full check up for a hefty sum but not sure if they can find the problem. Have spoken to them recently agin & they are just after the money but no advise as what the issue is or if they have encounter this in past. I drove on Motorway for couple of hours & not issue any problem for nearly a week. NOW parked & went for drive to work etc & it started back again. I did go to a local garage & they could not see any issue with their gadgets!
Many many thanks for reading & looking forward for positive feedback/advise
