I use the Tooki phone on my 997 and it works very well. I bought my car second hand and the previous owner had it fitted. Good bluetooth connection and integrate very well with the PCM2 native features such as auto music mute when a call come in etc. also actively synchs the address book from my phone. this sets you back around £500. including fitting
