Johny99 Posted April 29, 2023 Report Share Posted April 29, 2023 Hi I’m new to the forum so apologies if this is in the wrong section. I have a 2013 981s Cayman with pcm 3.1 incl Bluetooth from factory with the Bose sound system. I find the audio quality of phone calls quite poor, lacking clarity and also slightly grainy. Can anyone else relate to this and if so has anyone come up with a solution/upgrade to fix this? I don’t think my speakers have an issue as other audio incl audio streaming over Bluetooth are all fine. Thank you Quote Link to comment Share on other sites More sharing options...
daz05 Posted May 1, 2023 Report Share Posted May 1, 2023 Mine is clear, this issue is most likely Bose related, all sound is processed through the bose amp, it would be worth looking to see if there are fault codes in Piwis. But first check if you have any water or moisture under the drivers seat. Quote Link to comment Share on other sites More sharing options...
Johny99 Posted May 3, 2023 Author Report Share Posted May 3, 2023 Thanks, I’ll have a look on both. Does it have to be piwis or is a generic reader as capable of picking the faults up too? Quote Link to comment Share on other sites More sharing options...

Patt Posted May 4, 2023 Report Share Posted May 4, 2023 You can adjust the volumes in the PCM settings. I've only had poor phone since fitting and using the apple car play pcb Quote Link to comment Share on other sites More sharing options...
