I have recently replaced my RB3 satnav after the screen just went. I bought a second RB3 (same model number), but when installed, there was no sound from the speakers. EVERYTHING else works. I have even bought another one, but the same problem! Any ideas?

My chrysler garage says it could be a software issue, but I'm not sure. Recently I brought it to another garage and they installed a different radio (without the satnav) and that works fine, good audio. What baffles me is that when they replaced it with the RB3 unit with the electronics (!) it works fine, wkith sound!, but as soon as the car is switch off and on again, their is no sound. This indcates to me te radio is fine, but the amp is not kicking in. At teh garage they measured the output signal from both the radios (with satnav and without satnav) and I was told that the output signal from the radio withy the satnav (RB3) to turn the amplifier on is not high enough, the current is too low?? Is this possible? They have also played the radio on the bench, and then there is sound, although very quiet, due to no amp.

The original RB3 unit was made in 2005 (my car is a voyager reg 06). The two if have bought are from 04 and 03. Could this be a problem? Have they made changes to the RB3, without chaning the model number?

I'm sorry for this lengthy thread, but I have tried almost everything and I just CAN'T get the audio to work!

Any help is greatly appreciated!
THANKS

 

I have a similar problem is that most times I start the car I get no sound from the radio, CD player and DVD player. Sometimes the radio sound will come on as soon as the ignition is turned on and then go off after 5 or 10 seconds. Sometimes it stays on for 30 seconds and then goes off. Occasionally, if it has stayed on for more than around 30 seconds it will remain on for the rest of the journey, no matter how long.

On a couple of occasions I have started the engine and had radio sound that cut out after 5 seconds. I then turned off and restarted. After around three of four restarts the radio remained on. However this is not a repeatable process - sometimes it works and sometimes it doesn't.

I'm reluctant to take the car to a main dealer or audio specialist at the moment as with an intermittent problem they probably won't find it. My local audio specialist has said they can spend an hour investigating for £55 but, obviously, can't guarantee any results.

Before I spend money on investigating, does anyone have experience of this problem? I've seen other posts about the RB3 unit draining the battery, but I don't seem to have that problem.

Thanks

 

NickF, I had exactly the same problem when I bought my 2007 Voyager. It didn't have any SatNav Disc(s) at all but I read somewhere, probably on this forum, that a firmware update would cure the intermittent problem with the sound.
I was able to find this supplier LATEST CHRYSLER 2011 SAT NAV MAP CD FOR ALL RB3 NAVIGATION and I bought the full set of discs because I do a lot of driving in Europe.
After inserting the first disc the RB3 indicated that it was going through the update process and it prompted me to do various things (can't remember what now) but after about 5 minutes of whirring noises and screen prompts, hey presto I had audio and it's been faultless ever since.

Perhaps this will also fix Falko's problem.

 

Hi AlanC,

Thanks for your reply. I also read somewhere that the 2011 update solves the problem and so have tried it and after 5 mins of whirring and re-booting I still have the same problem.

It does seem that the radio is more likely to work if it comes on with the ignition rather than being turned on after the engine is running, but I can't get it to work reliably.

 

Sorry that didn't work for you Nick. I must admit I was only half expecting it to work for me so I was very pleased when it did fix my problem. Like I said, mine has been fine ever since the update.
The only other thing I tried, before I ordered the discs I removed the negative lead from the cable for a few minutes. That didn't help my situation at the time but, clutching at straws, I wonder if it was a combination of that plus the new firmware that fixed it for me.

So, for the last three days or so the radio/satnav has worked every time I have turned on the ignition. Since I have had the car (about five weeks now) the display has always been bright white even when the lights were on, but for the first time yesterday evening when I turned on the lights the radio display changed to what are presumably night colours and is now much darker when the lights are on. Whether or not this is related to the unit now working more normally I don't know. Pleased that it is working OK, but no idea why it should suddenly do so!

 

First the good news. Since my last post up until this morning (10 days in all) the radio has worked perfectly. No problems with cutting out. Now the bad news. This morning I turned on the ignition, heard a few clicks in from the speakers, three seconds of radio sound and then nothing. The problem has returned .

The "clicks" sound like the noise of something being connected/disconnected from a hifi system when the amp is turned on (if anyone knows what I mean).

This is clearly a not uncommon problem, but has anyone found a solution to it yet?

 

I obviously tempted fate by saying that I'd fixed my problem because in the last week or so, after turning on the ignition, I just heard the 'thud' through the speakers. This has happened 2 or 3 times, one was only this morning, and on each occasion, the next time I have started the car the speakers have worked fine.

 

I made about four or five trips yesterday and the radio made the "thud" sounds ,worked for a few seconds and then the sound cut out. Today I have just made two trips and it worked perfectly. I don't know whether I am pleased that it works or frustrated that with an intermittent problem I'm never going to find the solution!

 

hi there!
do you have solution already?
i have same problem. It start with intrmittent loud popping sound with about 3 seconds interwall and have no sound radio or cd..
maybe radio itself or amplifier gone bad?
something else?
