Garmin RV 1090 Lane Assist Issue

If it aint broken, don't fix it?

FIX IT GARMIN .......

OK, you had a device that did not show lane view and you were advised to return it and the wording seems to indicate you did that. Are you saying the replacement unit is also not showing lane view?

My point was if the old gps met his needs, don't replace it, keep using it.

I updated my car's nav fw back in june. They fixed most of the bugs introduce in the previous update (or 2) and the system overall works relatively well (except for a few caveats not directly fw related). When the oct/nov update comes out, unless it introduces some new features (like wireless AA), I will NOT be updating.

I've had a couple of Garmin GPS units which did some form or another of interchange display. In that time, the question of which particular intersections would get which form of display seemed somewhat whimsical, and definitely changed with map updates and with model (3790 not the same as 3597)

I imagine that your unit which advertises itself to do LA probably really does--somewhere else than where you are using it. And I imagine that question is tied to the map. It is not likely to be an individual defect of your GPSr, though just possibly it might be a configuration error.

The great thing would be if other forum participants using your particular model of GPS would report here what kind of interchange visualization they see and where, and how it compares in that respect to other models to which they have access or memory.

I do sympathize. It is always a great pity to move backward.

Garmin has three navigational aids to help the driver choose the correct lane for his/her route. The three navigational aids are: 1) Lane Assist, 2) Junction View, and 3) Active Lane Guidance. References on the Garmin web site to these three navigational aids are:
"Lane Assist on Automotive Devices": (https://support.garmin.com/en-US/?faq=UeHyBH53sQ9riQy68jsj89)
"Junction View": (https://support.garmin.com/en-US/?faq=Umn3OMB08f3iXuuEyML7o6)
"Active Lane Guidance": (https://support.garmin.com/en-US/?faq=4Fxmjh3cKa0YEqV8DfGti6)
From the RV1090 Manual "Active Lane Guidance": (https://www8.garmin.com/manuals/webhelp/GUID-9FC76615-A91B-4...) displays a screen with "Lane Assist" in the upper left corner and "photoReal Junction View" in the upper right of the screen adding to the confusing nomenclature. It's unclear to me if the RV1090 supports the same "Active Lane Guidance" as found on other Garmin receivers (like the nüvi 3597) or just Lane Assist with Junction View. Do you see displays similar to the "Active Lane Guidance" reference above?
From the Garmin web site "The Lane Assist and Active Lane Guidance features are integrated into the map file and will display on compatible devices." Reference: "Lane Assist, Junction View, and 3D Building View Content in City Navigator NT Supplemental Maps/Downloadable Content": (https://support.garmin.com/en-US/?faq=8L63bObSSQ7oJBNagT9nr8). Junction View data is stored in a separate file. Over the years, the size of the .jcv has shrunk substantially for some devices. Plenty of posts on poi-factory discussing the different .jcv files sizes and formats for the different models. As an example the installed nüvi 855 .jcv file is ~26.6MB, rather than the 869MB "Large" .jcv file installed on other models. Is there a possibility that your RV1090 has a small .jcv file rather than a "Large" .jcv file?

I have the same issue with my RV 890 here in the US. I can't say LV fails to display 99% of the time but it is very infrequent. I just assumed it was the unit's design.

I always run with two GPS units booted anyway so I use my Nuvi 3597 or Driveluxe 51 for JV.

Not an ideal solution but it works for me.

I also face the same problem. It depends on Garmin's mood. On the same route (I-80) sometimes it shows the junction view, but sometimes it doesn't.
