New Bose Stereo Problems

Don't let the dealer BS you, it's a real hardware issue

I noticed my Bose in my 2008.5 GT was cutting out as I was driving it home from the friggin' lot.

Really sucked, but the dealer earnestly started troubleshooting everything for loose wires, blah blah. Luckily I was able to show the dealer how to repeat it on demand. They would try this and that and test it. You get the picture.

Turns out, it was the circuit board in the amplifier. Had to be under a load and vibrated (driving). Maybe they got a bad batch. This happens from time to time in electronics mfg. Like I said, under a load it's OK but add the vibe and it cuts out.

I could tell they didn't want to replace the unit but they eventually had to. The solution is definitely to replace the amplifier. It took 10 days, but they fixed it. It rocks now.(band2)

No no no. Most everybody here is having a software issue with the head unit. Which causes the 34-35 issue vibration or no vibration, the bass cut out is also vibration or no vibration. And it's affected the poor folks like me that don't even have bose.. Meaning no external amp to go bad. Not saying you didnt have a problem with your amp, but thats not what happening with most the people on this thread. Do you still have the 34-35 issue?
 
Hey Hey Update.. Jst dropped mine off to get a new stereo unit installed.. Mazda's Official line is that they know s***.. but from the time I cam in a set up my appointment where they claimed they would investigate and the time I actually got the car in.. I went and said come on and I'll take you for a drive and show you the problem... my service guy told me no need he had already ordered me the necessary parts :) .. So I'm pretty sure Mazda knows exactly whats going on.. they just want to replace these quitely rather than say RECALL.. because they have likely fixed the problem in the future runs of the car.. my understanding is that its only a problem for those of us who got the first few off the lot. Cheers and I'll let you all know how it sounds when I pick it up on Monday..

Peace from Canada
 
My service manager still didn't call me back. He's trying to find the issue, but for some reason, I don't think he will since it won't be listed anywhere on Mazda's official channels.

Maybe I should drive up there and reproduce it to him.

I'm glad to hear that the new units also have better sound quality. I really didn't want to change anything on my car. The MS3 was a car I vowed not to change anything for a good long time. I just don't like the feel of tearing ANYTHING apart on a brand new car even to improve the sound system. As for performance, I want to see how well I do autoXing in D-Stock.

This is the first car I actually WANT to keep stock. Though I know one day I'll crack. :)
 
I had my new one installed yesterday...but the dumb s**** ordered the wrong one, and supposedly you can't tell until its installed. so they had to order a new one and they proceeded to tell me they don't even know if this is the right one, and that there is no way to tell.....BUUUUUULLLLL SSHHHIIIITTTTT. So now im going back today to get the other one they ordered installed. ******* stealership

I agree... I sure don't want the dash opened up and then simply have the faulty unit replaced with another faulty unit...

Please report back if/when the swap happens and let us know if it fixes the problem!

I wonder why they're so apt to order a new headunit but they're confirming theres no tsb or news from mazda regarding it. If it were me, I'd still be concerned that the new headunit would do the same thing.

This is what i've been afraid of the entire time. Ghost--what were you able to reference to determine it was the wrong one? Is there a different part no. on the back of the radio or did the tech order one with a different part no? Let me know so I can keep a look out on mine when it gets here.
 
I have an appt on 4-28-08 to get mine looked at. I called Mazda Corp. twice, and called my dealer twice about it, they claim there is no issue with them, and that this is the first they've heard of it. This is complete bulls***, why can mazda not log these issues on their tech site? Are they really in the ******* stone age of communications technology. Instead I have to go in, argue with them that there even is a problem, then they'll prob destroy my dash and replace it with another POS unit. I'm confident that my dealer really is in the dark here about the situation and he seemed very helpful. Mazda corp was borderline rude, and is lieing out their ass if they say there are no tech notes anywhere that 100 people have called in about this issue.
 
just called my dealer, my new head unit came in, but they are backed up in service today, looks like I will be waiting until monday @ 3pm to fix this problem :(
 
Experienced the bass cutting for the first time the other day. All I can say is HOLY s*** -- how significant!! I was listening to the radio past 35 for about 5 minutes and all of a sudden it's like someone pulled the plug on the lows.
 
All I can say is that your lucky you go 5 minutes. Mine is on off on off on off. If I change the volume up or down it comes back for 10 seconds or so...
 
Sirius Channel Preset issue with updated Radio

Ok, here's an update on my Radio situation. The Dealer took the radio out and had it re-flashed by Mazda in Syracuse, NY. While my car was going to be having "surgery", I had them install the OEM Sirius Tuner as well.

So, the 34-35 volume/eq issue is now gone just as many have reported here. The Stereo sounds great!

HOWEVER! There appears to be a very strange issue still with the HU. When I'm using Sirius, I can set Preset Channels 1-6 in any of the three banks for all Sirius Channels except channels 25-77. Now while you're on say Channel 33 (listening to the music) and you press and hold Preset 1 (or any other of the 6) to save the location, the radio beeps and confirms that you've saved this channel (music still playing from Ch 33). But if you go away from that channel and press Preset 1 again, you get "INVALID CHANNEL" and it stays on the last channel you were on that wasn't 25-77.

I brought my car in the next day and showed the Audio/Electronics expert this along with the service manager. They saw it with their own eyes and I could tell that they are quite embarraced about the quality problems with audio systems that corporate Mazda is letting out the door.

I'm upset, my dealer is upset, and Corporate Mazda is hearing about it loud and clear. They are saying that it may be another issue with the radio but that's all I know so far.

Anyone else hitting this? BTW, the OEM Sirius is different on this new radio than the ones they used for the non-updated (2008.5) radios. At least that is what I was told.

Please chime in if you can't Preset Sirius channels 25-77.

Thanks!

Just wanted to let everyone know, my 2008.5 stereo problem appears to be fixed for now. They ordered and replaced the head unit. Installation took about an hour. They said mine was the first one that has been brought to their attention. While I was waiting, A young guy in another 2008.5 rolled up and reported his stereo with bass cutting out. They had a mechanic come up and verify, same exact issue as mine. He assured the customer they will order a head unit and it will be fine. LOL...
 
Does anyone have an 2008.5 where the original stereo works fine as is? Just curious if this issue is hit and miss, or all of them....
