Not natively, no.

There's ways to trick Sync 3 into displaying it but you're either looking at a Lockpick (pricey) or a homebrew Arduino solution.

I put an apim extension cable behind my touchscreen with an arduino, using the Shift + / - buttons on the shifter to request camera view and switch to an aftermarket front camera. No factory wiring was modified but larger scope than you're asking for.

The no-wire solution would be an Arduino connected to the obdii port, triggered by pressing Eject or something. Downside is the 12v pin is always hot and would draw a constant 25mA or so even when the car is off (which isn't much, really). Maybe $25 in parts.

The theory of operation behind it is that on vehicles with factory 360 camera, the image processor sends a Camera Request message to the radio. The Lockpick or Arduino will send a message to the radio indicating you're at a stop, then immediately sends one requesting the camera.
