PDR Audio Quality
Howdy Racefans.. I want to post a query out to anyone that has PDR in their car.. "When you use your PDR, does the audio come out sounding like CRAP?" My stereo sounds awesome normally, but when I played the PDR recording I thought I must have blown a speaker!! Honestly, it sounds like the microphone is rattling around and you can actually hear it react to the various road bumps slowly driving down the street! I removed the memory card to make sure the noise was on the audio and not some sudden speaker failure, but it's definitely noise in the recording.. Sounds even worse if you listen with earbuds. Is anyone else experiencing this issue? Does anyone know if the microphone is accessible? PDR is a sweet feature to have not only for monitoring performance, but it's a pretty sweet dashcam as well if I can get the sound squared away! Thanks for any ideas you might have on this!!

The recordings are all very clear, both in the car and on my home computer.. It just sounds like the microphone is loose and banging against the framework or the trim.. something. With every little bump in the road, there is the associated "clacking" of something in there that is obviously loose and it sounds like it's being played through a blown speaker.. The system is still useful for the data that it can provide but, I'll be turning the volume full off. It's just too aggravating to listen to! Thanks for your replies!

Here's what one of mine sounds like for comparison:

It is hard to tell where the PDR gets its sound from. The best I can tell is it gets its sound from the HMI module which uses the cell phone microphone as its sound source. If that is the microphone it is located at the top of the driver's side A pillar. To check to see if it is loose you will need to remove the A pillar trim.

Recording Audio (or not) is one of the PDR Settings shown in my 2019 Owner's Manual...
I don't see it in the 2015 OM....

I found out the speaker for the PDR is right there by the mirror, along with the camera. By tapping on the plastic cover I can tell that it's loose enough to have a slight rattle. That must be what i'm hearing.. I also noticed that on good asphalt (the kind they have on highways and not generally on neighborhood streets) the audio is completely acceptable. I think I'm going to have to say the blame most likely lies with me! I was looking for Bose quality sound and forgetting that the audio really isn't the cool part of the PDR.. On a different note, I think I know why the guy who owned this before me sold it after only driving it about 15,000 miles.. You get used to the power pretty quickly I'm thinkin.. and then your mind begins wondering about ZO6's.. THANKS for all the help guys! You meet the nicest people in a Corvette!

Has anyone successfully shut off the sound on their PDR recordings? I like recording the drive, but don't want the chit chat.
These two comments contradict each other. Can you explain since the audio is not presented to the PDR user until the PDR user is in the playback mode. I listen to the radio not the pdr camera and doubt if I even could listen in real-time to the pdr while recording. I record all the time since I use the PDR as an insurance camera and spend five minutes of my life that I'll never get back each time I set up a PDR recording.

Don't you mean microphone??

I'd rather not have the in car chit chat on the sd card recording. It doesn't seem like it is possible to omit.
