Usb stereo

[Buggyeye]

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

I take it "Aux in " doesn't show up either? Looks like it uses the same channel for both USB and the Aux-In.

No the aux shows up and works fine just not the usb option

What device are you using?

Bluetooth adapter thingy. It has power but just the option for usb doesn't show up

Do you have anything connected to the Bluetooth when you're searching on the Stereo?

[Buggyeye]

Yeah my phone I'm guessing it can't find it cause it doesn't have any storage

I have a problem with connections to my phone sometimes if it is locked with a security lock/pin code.

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

[Buggyeye]

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 :)

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
