upload iphone contacts to lexus gs300
I have a Lexus 2006 GS300 with Navi System. My iphone 4 connects to the vehicle via bluetooth and it works well with making and receiving calls. However I tried to upload my iphone contacts to Lexus, it comes with issue. The vehicle asks me to transfer contacts from my phone. But iphone does not have such capability in sending contacts via bluetooth.
Does anyone manage to do this? Or any third party apps are required?
Thank you!!
