Radio has no sound; CD has little but garbled sound

[dawn555]

Problem with my '06 Murano SL AWD with Nav; one time I was driving I heard a loud "pop" and noticed a burning smell. After that radio is no longer producing any sound. When I switch to CD, I hear some sound but it's totally garbled. When I enable the navigation, the guide voice produces some sound but it can barely be heard. I should say the radio has been replaced before but that was due to a CD changer problem.

I took my Mo to a dealer for this new problem and I was told I'm looking at around $230 to take the unit out and "diagnose". Yikes I thought. I'm hoping to find someone who can advise as to what could the problem be? I don't know whether to leave it to the dealer or take it to some car audio shop to look at. I'm' beyond warranty (41k) and totally disappointed to have this problem at a fairly new car. Thanks in advance

dawn555-

A loud pop followed by a burning smell is not a good sign. Most likely the radio is a goner.

Unless you recently hit the lottery I would avoid the dealer at all costs. I believe the MSRP on the OEM radio is close to $1,000.

There is an outfit in Massachusetts that will take your unit and repair it for a flat fee - $147 to $187 depending on model. Here is a link to their site: Audio & Video Service Stop

Several members have shipped their radios to this place and I believe all but one have been satisfied with their work.

There may be an outfit like this in your area. Check the yellow pages and the internet.

thanks njjoe.

out of fear or mistrust of the non-familiar with the Murano configuration, I ended up driving into a dealership to get them to check what's going on.

They opened up the radio and found a couple of pennies lodged into the switch assembly, and they have become sticky and looked like they have begun to melt into the board. i should say though that i have a soon-to-be 3-year old son who i'm sure is the culprit.

so initially this was thought to be the problem. had that part replaced, but - problem not solved.

so now they're on to the amplifier. after the A/V switch assembly was replaced, their inspection shows power is now coming into the amplifier, but "has internal failure". they suggest going this route first before looking at getting the radio/cd replaced.

would you, or anyone, think a couple of pennies could cause this much damage, say even to the amplifier, when in fact it didn't really make a difference even when the switch assembly was replaced? i don't know if it was coincidental that there happened to be a couple coins there, but that the amplifier was about to go out anyways. I called Nissan Corp. Consumer Affairs before my first trip to the dealership and they said get the diagnostics first before calling them back (lady gave me her direct# to contact) and see what they can do about warranty - even though i'm beyond warranty. I don't know if that's just BS or they try to work something out if you persist.

anyway, long story short, i looked at these repair shops that many here ship to and i'm interested in going this repair route rather than replace. i just wish i know how to take those parts down myself!

i'd appreciate any input you or other experts here may have. i'm just really at a loss as to how to approach this problem now. all i know, i really don't want to spend much anymore!

thanks in advance, hope you have a great weekend!

YES a couple of pennies can burn up an entire radio. these radios have several microprocessors in them. one short even for a millisecond and poof you can kill a radio, nav, AC, the whole thing dead!!!

Before sending it to one of those shops. I might be able to help if you are in the US. i have done a great deal of work on these radios and have some parts on hand.

another option is to hunt eBay. i have purchased several of these radios now pretty cheap but you have to watch eBay for a while before you find a deal.

I noticed I have the left channel cutout issue when playing CD. When I have nothing better to do I will try to tackle it but if I can't, it will be coming your way Zero Cool...

By the way, good to see you posting again.

I was wondering if you got this problem resolved as i am having the same problem with my 2003 murano radio.??

[sarahg929]

Did you get this problem fixed and how? I am having the same exact problem with my 2003 murano.

sounds like a wiring issue I had in my 05 Audi A4 money pit edition... inspect the wiring harness to and in the door panel. There may be cracked and exposed wires in the harness, which is causing shorts to occur. As I said this occurred in my Audi with very similar symptoms. Once the wires were repaired, everything was fine.

The reason this was a problem was because the really thin wires and casings wear out over years of being flexed by the opening and closing of the doors, until eventually they crack. This is worse in cold weather as the casing gets brittle.
