EU Do you have Navigation? Yes What region is your SYNC APIM? EU What was your old SYNC Version? 3.0 Hi, Im getting a rear reverse camera installed soon which will link into the existing sync 3 unit. Im currently on version 3.0 19205 I have the 3.4 downloaded and ready to go on a USB but im hesitating a bit because will updating to 3.4 maybe affect when i get the camera installed on the back? Cheers I’ve just found after they installed a reverse camera this wire was left in my cup holder ![image](https://community.cyanlabs.net/uploads/default/original/2X/e/ef7cec5d22a5d7773c4f33928ceb894f86b9acb8.jpeg) Is this something related to why my USB ports don’t work anymore? Like I said my USBS worked absolutely fine on your 3.4 sync3 before this reverse camera was installed Many thanks for your help ---

Hello there. It’s never good to find an unconnected wire lying around, but I do not know if that is wire is related somehow to the USB ports. Lets see if anyone else has some insight about what that wire may be. ---

That looks like a APIM to screen cable, more technically known as a LVDS cable ![image](https://community.cyanlabs.net/uploads/default/original/2X/8/805b944b79f8d091a83d1c9f1d9a8cd24cb543cd.jpeg) ---

I’ve pulled the USB hub out from under the arm rest and all wires connected. Do these lead into the back sync 3 unit somewhere which they might of not connected back in? ---

You have some Mini USB style connectors on the APIM that the USB hubs will eventually go to ---

Nice thanks - it’s getting pulled out again on Friday so I’m hoping it’s these haven’t been connected again and that’s the problem. ---

on a Focus it takes like 5 minutes to get to the APIM, trust me i know, i did it like 30 times in my old Focus ST 😆 just double check all the wires and you can also try using a mini usb adapter and plugging a USB directly in (not that you likely have one, but you can get them on amazon pretty easily) [https://www.amazon.co.uk/TECHGEAR-Mini-Adapter-Cable-Host/dp/B00DM6EMQ2](https://www.amazon.co.uk/TECHGEAR-Mini-Adapter-Cable-Host/dp/B00DM6EMQ2) ---

Of course this only covers the data connection, they also have power connections in the hub aswell ---

There are 2 cable connections on the USB hub. A usb connection and a power connection. Based on your model year, you’re looking for a plug with 2 rows of 4 pins that will fit onto the USB hub on the rear. The connector is possibly white. ---

I would say it’s black not white but the rest matches up with my old focus ---
