In short. The jeep was parked up for the last for 10 days( for no fault of its own). Had to go on a trip yesterday 200km round trip. Went out last night to start up the jeep and noticed both the radio and sat nav screen were both dark... I did a quick search on the forum. I checked the 3 fuses that relate to the radio All were ok.

I hadn't much time to spend investigating. So I set off on my trip with no radio or nav.

I'm just in the door now do I'm seeking sum advice.

well i would start buy checking the headunit has power.

I assume nothing is displayed on the green headunit display? No clock ?

No errors on screen. And no clock also

Update.

All fuses are ok no problem there. Still both nav and radio are dead.

Where to look next

Just did a hard reset and noticed the led lights going into the cd changer flashing?????

how old is the car battery ? it might need changing.

In a bmw m3 I owned, I would regularly have an issue where the Nav/TV would not turn on. I would basically have to "reboot" the system, and did this buy pulling the +/- on the car battery for about 60secs and reconnect. They would come back working after that.

2006 vehicle

Battery is 3 years (Bosch).

Did 2 hard resets (different evenings). No improvement

Time to book in with my local independent.


I'll be sickened if it turns out to be some thing simple

Had a similar issue on my old RRS 2005.
Headunit was dead, no radio, no sat nav, no sound.
Ended up having to replace optical loop, once done all was fine
