Experiences with btp3gsm Bluetooth car phone adapter

[walthefl]

Hi, I am thinking about getting the btp3gsm from d5t5 to upgrade the gsm car phone of my 2008 Volvo c70 to Bluetooth.

I’d love to hear some opinions and experiences of someone who uses the btp3gsm.
How is it compared to the factory Volvo Bluetooth handsfree?
Is it easy to call contacts via the car interface?
Does somebody have the optional Bluetooth music extension and if yes how does it work and what option did you choose?
I would love to hear some feedback since couldn’t find any feedback elsewhere.

Many thanks
