Guam is due East from Manila. Guam's Street View coverage includes a visible long antenna at the front of the car, similar to the Northern Mariana Islands. The easiest way to tell them apart is that Guam has larger and busier streets, and has concrete utility poles, whereas the Northern Mariana Islands has more wooden poles. Guam is generally wealthier too. You may confuse Guam and the Northern Mariana Islands with Puerto Rico since they all have the same front antenna on the Google car, but remember that Puerto Rico uses Spanish and cars rarely have front license plates there.

The biggest tell for Guam, Northern Mariana Islands, and Puerto Rico is the large antenna on the front right corner of the camera car. Also, the car used to document Guam has a slight unblurred roof rack, which is useful in distinguishing it from Northern Mariana Islands.
