Telephone Module Microphone Location

[sneakybear]

Hi guys,

I have the telephone module in my 997.1 with PCM 2.1 - it has a sim card slot and it makes and receives calls almost perfectly. The microphone is the issue and seems to be the weakest link here as anyone I call hears a lot of static/road noise/etc over my chatter.

Where is the microphone and is there anything I can do to the system to improve it?
Do they fail? Would a new microphone help for instance... or am I just going to have to live with it.

I asked OPC and they said "They all do that sir", which is coincidentally the first time I've heard the exact phrase!

Anyone any experience/better ideas on here?

Many thanks,
sb

I know on the Gen 2 Cayman its in on the steering wheel assembly, you can clearly see two sets of perforations (on the right and left), if ever the person I am speaking to is having trouble hearing me I lean a bit closer.

Not sure if its the same on the 997 - have a look?

This was a well known problem with the 997.1. Porsche was supposed to come up with a fix but hadn't done at the time I sold mine in 2010. I think the microphone was in the steering column but my OPC relocated it to close to my sun visor to try and help matters. Do you have Bose?

Mic is in the column trim - under the perforated grille - std fit from factory was on the lhs of the trim. There is a two disc phone SW upgrade available to rewrite the noise cancellation parameters - essentially the cancellation function cannot differentiate between unwanted noises and the driver's voice in certain tones/pitch ranges.

Get the mic position checked and moved to the rhs of the trim and have the phone SW updated by your OPC - the issue is well documented and PCGB fought the phone manufacturer hard to accept the quality issue in the first place - might as well make the MOST of it

Thanks guys, great info!

I've not got Bose - does that change things significantly re the SW (or even position)?

As it's at OPC today I'll enquire about the SW update and microphone moving to the sun visor now...

Cheers,
