Hi Guys I have just purchased a c5 2006 1.6 VTX+ Nav , I love it, it has hands free but I have to keep removing my sim card from my phone and placing it in the head unit, which is most inconvenient, is there any way of up grading it to work via Bluetooth, also I have one more question my sat nav wont accept post codes can this be upgraded at all to accept post code searches. Thanks in advance
