August 11, 201510 yr Hi all I got a jvc kw-xr411 that has a usb port but it doesn't seem to show up when changing sources I used it the other week but I can't find anything online as it's a few years old now so any help would be great Sent from my SM-N910F using Tapatalk
August 11, 201510 yr I take it "Aux in " doesn't show up either? Looks like it uses the same channel for both USB and the Aux-In.
August 11, 201510 yr Author No the aux shows up and works fine just not the usb option Sent from my SM-N910F using Tapatalk
August 12, 201510 yr Author Bluetooth adapter thingy. It has power but just the option for usb doesn't show up Sent from my SM-N910F using Tapatalk
August 12, 201510 yr Do you have anything connected to the Bluetooth when you're searching on the stereo?
August 12, 201510 yr Author Yeah my phone I'm guessing it can't find it cause it doesn't have any storage Sent from my SM-N910F using Tapatalk
August 12, 201510 yr I have a problem with connections to my phone sometimes if it is locked with a security lock/pin code.
August 12, 201510 yr What size usb storage device are you trying to plug in ? Some older stereo's can't read anything above 4gig. Thought mine was broken until I tried smaller capacity sticks which work fine
August 12, 201510 yr Author It's a Bluetooth adapter so doesn't have internal memory I assume it just won't read anything unless it has actual data then? Not to worry I needed an excuse to get a new stereo without the missus whining :) Sent from my SM-N910F using Tapatalk
August 12, 201510 yr Ah maybe I know my plug in won't read above 4gig was worth a shot, same with my phone used to be able to upload phone book into head unit but it refuses to read now
