This is a brand-new Toyota OEM Bluetooth Handsfree carkit. This kit is the model PZ409-9029A-00 (PZ4099039A00) made by Motorola. It features speaker-independent (no training required) voice recognition for easy dialing and system setup (pairing of phones, switching between phones, etc.). I used to work at Motorola Automotive and had this in my leftover parts. This kit was for the Toyota Aygo, and includes the relay and handsfree integration harness to connect to the factory radio. The radio will Mute and switch to the Bluetooth system audio when in use. This kit is a version of the Motorola IHF- series Bluetooth carkit that was created for Toyota in Europe. This kit also features the Toyota logo on the IHF button assembly. Included in the kit are: PZ409-00292-01 - MOT T16TY01021 - Bluetooth Carkit ECU 0143700Z03 - Toyota IHF UIM 0143730Z01 - IHF microphone 3042260Z02 - IHF power harness PZ409-9027001 - Handfree Integration harness for Toyota Aygo 0141565Z01 - Handsfree relay CFBN1260A and 7541817Z02 - installation accessories Once installed in the vehicle, all that is visible is the small and easy-to-use keypad and the "mini-mouse" i microphone. Attachment is with tape/velcro, so there are no holes needed, either! I also have other Toyota Bluetooth parts from that era in my booth. Thanks for looking!
