OK...So I received a mail from Mazda to go to my dealer to get the M-flash and I did. Since I had a rattling sound coming from driver's side vent, I also asked that to be fixed.

When I get my car back, the tweeter on the driver's side was not working. There was no sound coming from it and when I adjust the mirrors (either sides) I will hear some static noise from that tweeter. Seems like the electricity from the mirror motors are coupled into the tweeter. Dont know what the hell they did to my car, so I went back to get it fixed.

They say it was a damaged radio and it sounded plausible. Seems like they are trying to replace whatever they can find until the problem goes away (or the complaint goes away). They say that they fixed the rattling noise by fixing the plastic clip on the A-pillar vent. So they must have taken apart the instrument panel and dash to get to the vent clip. This could be the cause for the damage, but they insisted that they never took it apart. The rattling did not went away, so it could be that they never fixed it. But why would they lie that they readjusted the vent clip?

So wondering if any one has any clue on what the problem may be. I dont want stupid dealers to take apart a perfectly working radio and find out that it didnt fix the problem. And I definetly dont want them adding more problems to my car and when I go there again they will say its not their fault.

Could it be that they fried my radio when updating the flash? What is involved in getting the M-flash so that I know they actually did it. I see no mod stickers and I tried the oil gauge sweep thingy with no luck. If they can lie about the plastic clip, they can lie about the M-flash.

 

The flash involves hooking the WDS to the OBD-II connector under the dash..

The left door and it's contents are really not involved.
