OP- if you're getting just the sportpackage just get an aftermarket HU and camera. check out the audio section where some are discussing about the camera that mounts to the rear license plate lamp. it's got reference lines and all.
since i hated the base HU that was the first thing i swapped out. the rearview camera is very useful and even without the reference lines on mine i can still park in reverse just looking at the HU's image.
