anyone recognise these parts? I purchased the unit from this site a year or so ago as a spare unit and it came with these. I just pushed it to the back of a cupboard until the day I'd need it. Passed it over to my mate to use as a spare now but can't for the life of me remember what they are! I seem to remember that one might be for connecting audio such as an iPod or similar.... (other mp3 devices are available)..... I was hoping that the other was a bluetooth module (old style). any thoughts?
