Thanks for this, me thinks though i will ask somebody in the know (not me for sure) to do this, for a fee of course? Can i ask to all plse if there is anybody in the South Yorkshire area who (and name your price) could get rid of this rattle for me, which probably means taking my rns510 out, filling in area with some foam, etc perhaps and then installing the unit back in?
Many thanks in advance for any offers/information
Andrew
