Others have got the iPhone 5S connected and working - see here :
Trophy SE/Sena SMH10Rv5.1/Garmin 590LMWhen you get the "NO DEVICE" message on the Instrument Panel,
is this with the iPhone connected by USB to the Trophy USB Port in the Glove box ?
If an iPod or iPhone is connected to the USB, then "iPod" should be available to select
when scrolling through the list of available Audio Sources.
( If another compatible USB device such as a Memory stick is connected to the USB Port
then the Audio Source would be listed as "USB" ).
Try switching OFF the audio system ( Turn Volume down all the way past Minimum until the display says "AUDiO OFF" )
then, with the iPhone "unlocked" connect it by USB, then turn the Audio System back ON ( Volume UP ),
and then allow a few seconds for the Audio System to recognise the iPhone and read its contents.
If it doesn't show up at all, try another USB Cable that is known to work,
as even the genuine Apple cables are prone to failure !
Cheers
