Junction Views

Junction Views occur whenever the GPS needs you to choose from, say, three different paths you might take. This usually only occurs in large cities which have multiple intersecting freeways and highways.

Garmin describes Junction View as

"Realistically displays 3-D road signs and junctions on your route while clearly marking the correct lane to use. It makes driving so much easier when you know exactly which lane to be in and which exit to take. "

However, most of the time all one sees is "Lane Assist" arrows which Garmin describes as

"Provides arrows that indicate the proper exit lane for complicated highway interchanges so that they are easier to navigate. You’ll know in plenty of time which lane to be in for the next turn. "

Although I know most people would prefer to have Junction View at every point of choice, what we almost always get is Lane Assist.

If you're looking to test the feature out, you have to simulate a route in the GPS. I find simulating a trip from T.F. Green Airport in Providence to a favorite of mine in Moncton, NB works well enough. In any event, let the GPS calculate the route but don't run it. Tap on the banner bar and it shows the list of turns. Tap on a turn to show the turn. If a junction view is available, the Junction View will automatically appear. For example, in my simulated route, the following turns have Junction Views:

Providence, RI
*Keep left on I-95.

Boston, MA
*Take Exit 12 on right to I-93 N towards Boston.
*Keep left onto I-93 N/US-1 N/RT-3 N towards Boston.
*Take ramp to I-95 N on right towards N.H./Maine.

New Brunswick
*Keep right onto Hwy-2 E/TransCanada Hwy towards Fredericton.
*Keep right onto Hwy-2 towards Hwy-7/Airport/Moncton.
*Take Exit 454 on right towards Mapleton Rd. NOTE: This one shows only because of my favorite's location. It may not show in a simulated run to the center of Moncton itself.

As noted already, the thing most commonly seen is the lane assist arrows. This is because they are built into the firmware, unlike Junction View, which takes anywhere from 100MB to 650MB, depending on whether the Junction Views are the standard version or whether they are photo-realistic (high quality) views.
