[EDIT] New version available at: POI Scanner for Microsoft Streets & Trips
I've just finished a POI Scanner for Microsoft Streets and Trips. This Scanner functions by determining the zoom level range by locating the zoom level in the tracker bar. Then it locates the first dark burgundy pixels in the GPS icon. Once this is known it searches for a pink pixel located in the maroon tack or maroon flag.
If it detects the POI within approximately 500 meters when scanning, it will beep quickly 5 times, then beep once every 20 seconds until you have cleared the POI by 500 meters. The beep is independent of the volume control. Even when the volume is muted the beep will function.
To use this tracker:
1) You must NOT use the red tack, it contains the same colour of burgundy pixels of the GPS icon.
2) You must use the maroon tack or maroon flag for the POI.
3) Avoid using custom made POI which contains pixels of the same colour as the burgundy or pink pixels used in search.
4) Hide places that use the purple icons in Find Nearby Places to avoid false positives recognitions of the maroon tack.
Settings used in testing:
Windows XP normal colours.
This POI was made on a resolution of 1280X800 pixels. It is set to scan for a distance of approximately 500 meters. Using a larger resolution should result in reducing the distance of 500 meters since there will be more pixels.

I do not expect it to work completely in other resolutions yet. I've tested lower resolutions and the zoom track bar appears to remain functional in all resolutions. That's good news. What changes is the scan distance. As the resolution lowers, the distance increases. I expect it to decrease as the resolution increases. I've included the source code if you are interested in modifying the scan distance settings as you wish for your personal use.
Zoom pixel are to set the distance to search for:
$Zoom_pixel_1 = 310
$Zoom_pixel_2 = 109
$Zoom_pixel_3 = 37
$Zoom_pixel_4 = 15
I made a short video of the POI Scanner to help in visualizing how it operates. It's uploaded it on Youtube.
Be sure to raise the volume on your system. It is somewhat low on this video clip.

It lasts one minute and eight seconds. In it I inserted a maroon flag to indicate a POI on the highway. I used the red tack to simulate the moving GPS icon. When it reaches a distance less than 500 meters, it beeps five times. I then approach the red tack nearer and 20 seconds after the initial quick 5 beeps, it beeps again once. I move back the tack farther than 500 meters for 20 seconds. The Beep counters resets. The next time it detects the POI, it sounds off 5 times again.
I'm sorry for the poor focus, the camera is of the cheap kind sold at Canadian Tire. It does not have a manual focus.
