1st post for me here !

just got a 2011 Qubo Trekking . at first usb was working randomly for music on 32gb stick now nothing .
tried all the methods for working but nothing. Still power light on on socket and stick .
Tried a blue&me dongle for iPhone - nothing
iPod nothing .
cleaned out socket with contact spray and compressed air - nothing.

So thinking it must be faulty socket not reading . new one from Fiat is £66 !!

any suggestions please ?

Also is the earlier usb socket part no. 735429751 the same as 735496444 on my car ?
many thanks

Ian
