A couple of weeks ago, I took a trip using routes I had created in BaseCamp and noticed the the Junction View was not working. I used the unit in late August on a 1,000+ mile round trip, and had noticed no problems. However, I believe there were updates available just before I left, but since I was worried about update problems, I didn't run the updates.
I did some digging online and discovered that I had two JCV files, neither of which matched my IMG file. I installed the available map update, and I had only one JCV file and one IMG file remaining, but the problem remained.
I created some simple "off the interstate, down the ramp, back on the interstate" test files in BaseCamp. They either do not work at all, or one junction will display and another won't. Prior to this, I never recall having a junction that did not display.
I have uninstalled and reinstalled the maps several times. I have tried copying the route to the unit and changing the calculation mode. I have reinstalled BaseCamp. I have Googled the problem, and searched the Garmin Forum and POI Forum.
I have updated my software to 8.70, and maps to North American 2018.30. I reinstalled maps to the unit today after deleting the JCV file (as recommended in a thread). I now have the JCV file is D3191240A.jcv (10/21/17 3:31 pm, 498548 KB), and a map file of gmapprom.img (11/4/17 12:56 pm, 2791744 KB).
I've seen several threads through the years, but I wanted to ask and see if anyone had difficulty that appeared starting in August or September this year.

Jim, I have an older 1450 with the large JCV file (that works). My JCV file is D3060250A.jcv and is 849,774 KB in size. I don't know if your unit uses the same jcv file as mine, but this is what I have.
Your 2639 is one of the models that has Active Lane Guidance. WIth each map update, Garmin continues to remove the static junction views on intersections where they add active lane guidance views.
Active lane guidance is not part of the junction view file, and when you select a route or destination then step through the turn-by-turns to look at the junction views, these active lane guidance intersections will not show the view. But when you actually navigate, they will show.
Until your reply, I didn't realize my model had Active Lane Guidance, and I had to hit YouTube to know what it is. I have never noticed it working previously. However, I have only traveled in Tennessee and Alabama, so perhaps it has not filtered down to where I've been.
When I first noticed the Junction View problem, it was while I was navigating. I should have added what I meant by "not working": I got the "bird's eye view" instead of the static Junction View.
I appreciate your info. I'm going to try some more troubleshooting, but I have about resigned myself to living with it and hoping for a correction in a future update. I also suspect that creating a route on the nuvi instead of in BaseCamp will work, but that will be a hassle for long trips.
I wish you luck in wishing and waiting for a "correction" on this, but I suspect Garmin will continue to remove the traditional static junction views with each map update for these higher end models with birds eye and active lane guidance. They also are removing some of the original "multi-arrow" lane guidance in the upper left corner. I personally wish Garmin had just left lane guidance and static split screen junction views like they were originally designed and continued to expand coverage. But then then their marketing division would not be able to tout some glitzy new feature to try to promote upgrades and replacements of the older devices.

Me too! We get quite a bit of Active lane guidance in UK and I find it confusing.
