Adding USB connection to 5" radio

I´m thinking of adding USB connection to my standard Pure 5" radio which I did not quote for when ordering. Does anybody know to where the USB connection is plugged into and how the connector/wiring looks like ?
I beleive it is connected to the rear of CD box but may be wrong. Thanks for any comments.

this is how the connector should look like from the back of CD unit:

A complete guess but have you checked with a meter to see if you have 5V on pins 1 and 4 (looks like it maybe a 4 pin connector) if so it'll likely be standard USB wiring...? You might be able to run an extension if you can find a connector that fits...?

no chance to measure as the power cabel is too short and both, power and usb connector are at the back of the unit. I will check with dealer if the original cable can be ordered.

I have tried whith a Honda adaptator which is the same connector, but it doesn't work.
Powwer supply of the usb key is ok but nothing with the data.
