FWIW, I don't think you can install 9w3 since it's a factory option. I'd like to get a Golf but the site FAQ says they only get 9w2 bluetooth? I think the cheapest OEM level option is the Fiscon bluetooth. http://kufatec.com/index.php?main_page=product_info&cPath=152&products_id=207 The benefit is that it also gives gauges in the MFD like actual ater temp, boost, and it works with the MFSW or touchscreen radio.
