Sad day last Saturday getting rid of the Mk5 GTI and bought my mrs a 2.0TDI 140ps Jetta instead,cheaper to run and big boot for the kids buggy and crap,still got the r32 for fun tho,this question has probably been asked before its a 2008, has standard Rcd300,i am thinking of retro fitting a media in kit into armrest and upgrading to a RNS510 as i have the combo in company car and find it great,has anybody had battery drain issues from these radios as i have heard the radios do not shut down so the board net unit stays awake hence draining battery?? Anyone done this?
