Split Screen Question

I just returned from a 950 mile road trip and didn't notice any problem like that.

with my 3597 on a 500 mile trip earlier this week. I had to stop navigating the route I was using and restart it to clear the junction view split screen. Worked fine after that.

I suspect it's a bug in the latest firmware / map update since I never experienced the problem prior to the update.

This has occured up a couple of times on my 3597. It stays till the next split screen shows up then things go back to normal.
BTW, we have many junctions around here where split screen is displayed.

I semi-retired my 750 after it started intermittently locking up last year and replaced it with a 3597. I've not seen the problem described here yet, but so far my trips with it have not exceeded 300 miles and being in a rural part of America, I don't often see the split screen pop up for junction views. If this becomes widespread, the last update is certainly suspect. If only a few experience the problem, it may be one of those glitches that can be cured with a hard reset. Some routinely perform a hard reset following each update to presumably purge any cruft that may cause odd behavior. Be aware that a hard reset will restore all settings to factory default and will likely flush any Saved (Favorites) places so if they are important to you, be sure they are backed up so that you can restore them.

Knowing that this is happening to others I also now strongly suspect it being either a firmware and or map issue.

In 1600 miles I just noticed this happen once so I wouldn't say the problem is severe but somewhat annoying.

It would be a good test for others that this happens to if possible, in driving on that same route some other time in trying to determine whether it's firmware or map related.

@ TXRVer I always do a hard reset after a map update and a firmware upgrade and did so when updating to the latest maps and firmware.

Thanks everyone for the feedback and let's keep an eye on this and see how this evolves with time

Nobody is stating what map and firmware version they are using on their 3597's that have experienced this issue in an attempt to identify when this appeared.

Something to consider, I’m not sure, but can it be the particular Junction View file itself. Perhaps there is a glitch in the file that is not triggering it to turn off once the exit has passed.

I suspect you are correct muell9k.

In my case the 3597 with "stuck" JV file is running software version 4.80, firmware version 3.05.10 with CNNT 2015.4 loaded. The stuck JV screen occurred on I-81 North in the Harrisburg, PA area.

I'm planning on making the same 500 mile trip later this week where I first noticed the issue. I'll report back with any developments.

Thanks for posting your software & map version. Have you traveled that route using 2015.30 or prior map versions and had no issues?

If member Canuk has same software & map when the issue appeared it's likely either the 2015.40 JCV file or the map itself is at fault. I'm sure you guys keep your firmware current so we can most likely rule that out.

I just recently got my 3597 and did a complete backup, update followed by a hard reset.

I also have Software version 4.80, Firmware version 3.05.10, 2015.40 maps and was using English Samantha.

I confirm at 100% that the lockup happened somewhere going north bound on Interstate 81 in the state of Pennsylvania but unfortunately don't remember of the exact location.

Perhaps if another member tells us the precise location of a lockup others could simulate a route with different versions of Nüvi's to see if it's map or unit related.

Since member bdhsfz6 stated his lockup was also in PA on Interstate 81, seems to me there is a glitch in the 2015.40 map and accompanying files. He states his lockup occurred Northbound near Harrisburg. Why not try a simulation route to that area and hopefully there may be some junction views prior to Harrisburg that don't lock it up.

If it only happens at Harrisburg then it's certainly not a firmware issue.
It's best to do the test on the Nuvi 3597 and not on other models in an attempt to pinpoint the cause.

Have you ever had this Junction View lockup occur on any prior map versions? If not, in all probability it is the fault of either the 2015.40 map or its corresponding JCV file.

A true test would have been if you had a backup of an older map version to copy it to the Nuvi with its JCV file and do a simulated route taking you North on I81 through Harrisburg PA.

Some long trips over the past few months and I have not experienced this issue. Many other ones (lol), but not this one.

I just got my 3597 a few weeks ago and coming home from Florida was my first true test of the unit and the only mapset I've ever used on it.

I'm hoping that fellow members bdhsfz6, dougcutler or someone else that this has happened to can give us a precise location so that we can further investigate in determining the cause of the lockup.

Bdhsfz6 mentioned that he was going on the same 500 mile trip this week therefore if it's map related it'll do it again and this time will know the exact location and can take it from there

I can confirm that the JV lockup did not occur with my 3597 on previous trips northbound on I-84 in Pennsylvania when running CNNT 2015.3 and the previous firmware version.

@canuk
I made the southbound leg of my trip on I-81 thru Harrisburg this morning with both my 3597 and RV760 booted. I experienced no split screen lockups. My brother followed me in his vehicle with another 3597 booted (same firmware and map update as previously reported) and likewise experienced no lockup.

We will both make the northbound leg of the trip Saturday and I'll report any incidents.

Stop driving north on any road, way, street, court, place, lane, state / county highway, any interstate, toll road, detour or bridge in Pa.!!!

I think that about covers it!

Well it appears it is in fact caused be a glitch in the 2015.40 map update. If all other Junction views work properly this is an isolated case. I would report it to Garmin and hopefully they will correct it in future updates. I'm still not sure if it's the map or the junction view file, this is why I say report it to Garmin rather than HERE (map creator).

I made the return leg of a 500 mile trip northbound on I-81 Saturday. I had both my 3597 and RV760 units booted. My brother, who was following me, also had his 3597 and 1490 units booted. Both 3597’s have software version 4.80, firmware version 3.05.10 with CNNT 2015.4 loaded. This time the frozen split JV screen issue that both canuk and I experienced on previous trips through this area did not show on any of the four GPSr’s.

The intersection in question is exit 70 on I-81 north. It is the junction of I-81 and I-83 in Harrisburg PA. I have been travelling this section of I-81 frequently for many years and have not seen the abnormality at this location, or any other for that matter, prior to the incident last week.

Whatever the problem, it does not appear to be a consistent one. Had canuk not reported it also at approximately the same time, I would have dismissed it as just a fluke.

Now knowing the problem is intermittent means that it's not necessarily a map problem

So far it's happened to three of us using a 3597 & it'll be interesting to see if other members using this unit along with other different models encounter this type of freezing/glitch down the pike.

My unit had no issues in the Dallas-Fort Worth area of Texas nor on long drips to Kansas, Missouri and Arizona prior to firmware update 4.80 and installation of City Navigator North America NT 2015.40.

My instance this morning was that the Junction View was not showing up as it typically used to do prior to the updates. Even my map appearance and driving routes presented and responded differently than prior to the updates.

I am using the Australian English TTS voice because the American English TTS was beginning to annoy me. It is not the voice itself, rather that the same voice is present on my Android phone and in my VW voice command system. It is too much like one entity all the time.

In any case, I have the *lack* of my Junction View displaying like it used to after the new updates. Perhaps it is simply me needing to fill it back up with my trip habits.

Welcome to The Factory. If I'm understanding correctly, you've lost all Junction Views after updating to the latest firmware and map on your nuvi 3597. This has not been seen by others so it's not a common issue.

The very first (since it's the easiest to do) is to fully power down, then power up the 3597. This is not the normal sleep setting but a real power down. Hold the power switch until you see the "Turn off the Device?" screen, then tap Off button.

Many folks routinely perform a hard reset after a firmware or map update while others (like me) perform a hard reset only if something doesn't seem right. I suggest you try a hard reset after backing up your Saved Places as your next attempt at a repair if the Power Down doesn't resolve things for you:

If this fixes things, then we're set. If not, there may have been a corrupt download or update. You could look at the files in your nuvi and see if certain files are present, their filesizes, etc. Shout if the hard reset fails and you want to try this.

If the map appearance, routing etc. appear different, you may want to check to see what your Map Layer, Map Detail, Navigation Avoidances, 3D/TrackUp/NorthUp and other settings are to see if one of the updates changed one or more of your earlier settings. Note that doing a hard reset will return ALL settings back to their factory defaults. I'm sure you know this already, but just to be sure, remember that Junction Views only appear when driving a route. JVs will not appear when the GPS has no destination set.

Many here are like you (and me) and use Karen, one of the Australian voices.

Be sure to let us know what happens. We will get this fixed.

One last request (unrelated to your stated questions): Do you see the shaded relief darkening to suggest hills and valleys, etc. on your normal map display? If not, we can look into this as well when delving into your files.

My roadways and highlighted routing look different, but I do see terrain shading.

I downloaded the updates last night and did the hard reboot (I am a tech nerd, so I know the difference) and it seemed fine. This morning, I did show *one* Junction View during my morning commute, about 4 miles from my destination. It appeared during the normal window in which it has typically appeared. However, the others that I usually have did not.

It cures a lot of ills and glitches after a map or firmware update. It's pesty to have to re-set all the preferences afterwards, but it has cured a few problems on 2595 from time to time.
