Scirocco Central

Looking at bluetooth kits, is the Fiscon Basic Plus any good? Have read a couple of reviews saying the VW type mic is not that good, was wondering if it's ok with a genuine mic?

I have a 2008 2.0 GT and want to replace the discs and pads but GSF have about 3 different sizes for both front and rear, and also pads with or without wear sensors. What size discs do I need pls and is there an easy way to check if my pads have wear sensors?
Thx

My 2008 Scirocco has the RNS510 with BT capability but but no BT module installed. Can someone recommend a company who can install a VW factory module so I can use my phone through the stereo as VW intended pls?
Thx

Forgot to mention that I'm in Ashford, Surrey / West London?
