Problem with using walkman connected to ford car usb

[colgreengrass]

Recently purchased a NWZ-E474 Walkman to replace older model NWZ-E436F which stopped working. However when I went to use the new one in my Ford car stereo it says USB device not supported whereas my old Walkman worked fine.

Can anyone help solve this?

Thanks

I have also purchased one and I want it to connect to my car (Audi) computer via USB, but the message displayed on the WALKMAN screen is "Connected USB MTP The player cannot be operated"

My NWZ- B170 works perfectly
