I'm really sorry if this is a duplicate for yet another radio issue, but I have looked through as many other posts as I can and while I have seen others have had the same issue, I am yet to find anyone who has solved the problem.

I have a 2004 Coupe 4200 Cambiocorsa and following a battery replacement, the radio has never worked again, I have been trying to find a solution for 2 years, taken it to various Audio "specialists" plus Maranello in Egham and no one has a clue how to fix it.

This is the screen I get and there is no audio at all.

138269


I have popped the unit out and checked the connections at the back (I am absolutely not technical in any way) but nothing is frayed or looks loose and seems to be fine.

Any help would be appreciated, at this stage I am ready to replace the unit with a second hand one, but these are still nearly £2k!!

Your screen appears to be functioning just fine. The issue appears to be either with your NIT (in the central arm rest) or the cable that connects it to the screen. The NIT has a red 10amp fuse which is easy enough to get access to - the cable less so as it connects to the underside of the unit. Fingers crossed its a simple fix.

Thank you SO much I can’t tell you how much I appreciate your help.
I got the fuse out of the unit (wanted to know exactly what I needed to buy) told you I am not technical at all!
Tomorrow I will grab a new one and try that
Thank you again!!!

You're welcome. Is the fuse blown?
It sure was! I have put the new fuse in now but now when I turn the engine on the info centre doesn’t light up at all
I don’t know if I’ve broken something when yanking that fuse out or if I’ve put it back in the wrong place. I haven’t taken the NIT unit out to do this. This car will honestly be the death of me!!
thankfully the air con is still working though!

Nonsense - its all fun :) Interesting though. Check the connections again as something may have been dislodged rummaging about for the fuse. Maybe try a battery reset - I can't imagine that would make any difference but worth a try. There is an isolation switch in the battery compartment. Make sure you leave a door open first or drop the window an inch - so the glass will clear the door seal. Leave the boot open too.

If no luck try taking the NIT fuse out and see if the screen functions again. There maybe a protection circuit but, tbh, I don't know. Do you have Auditorium 200? There will be badges above the large door speakers if so. If so, whatever caused the NIT fuse to blow may have done the same with the amplifier fuse. If not, I'm at loss as to what to suggest next. Maybe others can chine in.

There have been reports of a faulty NIT being repaired but if you can't track down the issue replacing or repairing original equipment would be pricey. There are a few suggestions above to try but if the issue is not a quick/cheap fix perhaps it would also be worth considering installing a modern stereo. There are a number of recent threads on that subject and updating 20 year old equipment has its merits.

I definitely wouldn’t call the last 2 days fun 🤣 I refused to give up and continued to fiddle around, I removed and replaced the new fuse which hadn’t blown and was definitely in the right place.

Another thread directed me to the fuse board under the passenger footwell access panel, and the fuse for the screen had blown! I can only guess I must have done that somehow with all my rummaging yesterday, but replaced that mini 15 amp one and just like that everything came to life and the radio came on for the first time in years, the stations were still even programmed! I cannot believe the problem was down to a fuse and cost no more than £2 to fix.
I cannot thank you enough for your help. I’m just so annoyed I didn’t come on here sooner!
Thank you again!!!

From memory Disconnect battery, wait a half hour. Reconnect, turn key to Mars position. Leave there for 5 minutes. Turn back to off. Start car.
