Problem; Everyone can hear me on the BT phone over the in car microphone but since my wife is soft spoken and she is in the passenger seat hardly anyone can hear her. Solution; Install two mic's up there. Problem; Lots of questions. Solution; Ask the great folks at Priuschat.com Pros; People will finaly be able to hear my wife in the car too and that would make her happy. Cons; If it can be done, it will cost around $70.00 to do the way I have priced it, and that would make her mad. :angry: Then I will be sad. Here is what I have so far: I always wanted to know what was behind the vent holes on the passenger side. [attachmentid=5247] After unscrewing two screws from the eyeglass holder area (Not Shown), pull down on the right side. [attachmentid=5248] Remove the clip holden the overhead lights to the roof. (Bad picture.) [attachmentid=5249] Remove the lamps/bulbs. [attachmentid=5250] Remove three more screws. [attachmentid=5251] Pull up the back of the board about a half inch and then pull it back and away from you to free it. You can see where the mic sits now. [attachmentid=5257] Notice the clip is a holder that would work on U.S. and Euro Prius. [attachmentid=5253] This is the box your after. You have to do the two clip on the underside with a flathead screwdriver first. [attachmentid=5254] Now you can see the Mic Amp board. This is the best picture I have of the mic connector. [attachmentid=5255] Here is the microphone. [attachmentid=5258] My dealerâ€™s part department gave me these part numbers for a replacement microphone with microphone amp. So that would include the black box also. Part number = 8625047020 or 8625047040? I went out to find another microphone and while I was out I started to think that I might want to go with the official Toyota part on this mod for sound quality. Well do you want to be part of a Prius-Think-Tank? Or would that be Prius-Think-Bladder? Anyway, here is what I need help with. 1. Can two microphones be hooked in parallel without any trouble? 2. How can I pull the pins from this clip so I can solder a second microphone to it? 3. What is the correct part number? 4. Can we find a source of this exact microphone without the microphone amp? 5. Is there a source for a dearly departed Prius where I could get just the working microphone for less then the $70.00? 6. Should I install a mini pushbutton on/off switch to turn on and off that microphone? I am thinking I can come back to that later and if I do I want to figure out how to hide that in the eye glass holder so you canâ€™t see it under normal circumstances. 7. Can you think of any problems with this mod that you think canâ€™t be overcome? 8. Is there anything you can think of that I have not though of. Thanks in advance for your help. If I have to, I will save my lunch money to get the $70.00 but I thought someone might know a source.
