Kufatec bluetooth upgrade for RNS E question.
Hi guys pretty new here recently purchased a 2.5TDI A4 avant from swine off here,he had previosuly retro fitted an RNS E unit (happy days) i am now looking to retro fit this kit from kufatec KUFATEC GmbH - FISCON Freisprecheinrichtung Audi, Seat "Basic-Plus" 36431 Will i encounter any issues due to the RNS E not being a factory fit? it also says on the kufatec site i'll need to do some coding to make it functional,anyone have an idea what coding is involved? i have VCDS.It also says on kufatec that my RNS E will need to have a software index of at least 350 how do i check this?
Thanks for reading
