Zoom Levels

 

So I saw several discussions about zoom levels, but I didn't quite see this question answered.
The issue: On my old 3760, the zoom levels worked perfectly to what I set them to. There are at least 6 zoom levels remembered:
1) "Normal speed" (below 58-60MPH) with and without an active route.
2) "Fast speed" (above 58-60MPH) with and without active route.
3) There was another level that could be set for on/off ramps with and without an active route.
4) There is also a "default" zoom when the device powers on and you have not moved yet or have not navigated to a road on the map, that seemed to be the same as "Fast speed".
My old GPSr transitioned between these zoom levels with no problem and ran very smoothly.

On my new 3597, the GPSr can't seem to recall the correct zoom levels I have set for the various conditions. Sometimes it remembers them, sometimes not. Sometimes it will start at the "default" zoom level and never go to the "normal" zoom when it locks to a road. I have to manually zoom in. When I do so, sometimes it will not zoom out to the "fast speed" when I go over 58-60MPH. I really like this new GPSr but the inconsistent behavior with the zoom levels is getting annoying.

SO ultimately, my question is: Are the zoom levels hardcoded on the GPSr, or is there a file on the GPSr that hold the zoom level values that I could edit to possibly fix this issue? And when I mean editing the zoom levels, I mean editing the distance of zoom at each of the 6 or so zoom levels. I do not mean editing the threshold of when the zoom level transitions.

I am not even aware of these

I am not even aware of these zoom settings. I have got 3597 and nuvicam but don't know the settings.

Not really settings

They're not really settings per se...it's just what you manually set the zoom level to in those instances and the GPSr remembers it.

Another feature removed

My 1490 remembers zoom settings too but my 2508 doesn't. The ability to remember zoom settings seems to have been removed on later nuvis.

My old 760 used to do all

My old 760 used to do all this automatically. Starting with my 2555 and 2597, the zoom methods changed. I posted about it a while back. Basically, a certain set of newer GPS won't zoom if there are no active routes. This same set will have speed zoom broken if you go to the menu screen while an active route is above 58 MPH and zoomed out. (Either zoom out manually, or stop the routed and turn the unit off by holding the off button, then restart and reenter your route). As far as the default zoom settings, the older units defaulted to 800 yard, the newer one default to .2 miles.

Zooming in on a off ramp should be function of routing, since that is normally a direction change and it should zoom in like another turn. Zoom on an on ramp the same. I've never seen any unit zoom for a turn when no active route exists.

All that said, I have a Dezl 760 and it zooms like the the old software and going to menus while zoomed doesn't affect zoom. It does zoom when not actively routing and going over 58 mph, but not as far as it does when routing. I can manually zoom it out, but after unzooming, (is that a word?) it won't zoom back out to the level I manually set, it goes back to a default zoom of .5 at speed.

Has that thoroughly confused you? Hope not, but feel free to ask specific questions. I'll try to answer.

The Honeymoon is Over

Hey Garmin: Bang Zoom!

My zoom is automatic

My zoom levels on my 2798LMT are fully automatic based upon speed and I've never seen a setting to change that based upon different speeds... only the level of detail shown on the map. I think a manual zoom in is only temporary but then again who knows...

Okay

That makes a lot of sense, but the weird thing is that the 3597 *sometimes* remembers what zoom levels I prefer at each different level. But *most* of the time the levels "reset" to the default setting. The lack of consistency is what confuses me. But since the GPSr does sometimes recall a previous zoom level I manually set, even after the power is off, I am hoping these values are stored in a file on the GPSr and can be edited manually? They definitely might be hardcoded, but a man can dream, right?

Thanks, Narvick

Marvick, thanks for the postings. The behavior that you described have been bugging me for a while. Thanks for posted such details and prcise descriptions. smile

I have observed similar bewildering behavior and I thought I was going bonkers.

The following is a summary of my observations:

1. On cold start, the 3597 does have the 6 factory-preset zoom levels that you described in the first post. The zoom levels can be manually changed as you have noted.

2. The zoom levels are remembered until another cold start that restores them to factory-preset values.

3. The zoom levels remain as set if the 3597 is actively routing.

4. If just cruising after the 3597 performed even just one single active routing, all the zoom level settings are lost, except zoom level (3) for on/off ramps.

You can still set the zoom levels manually, but when/after you enter/exit an ramp, all the zoom level reverts to level (3) and sticks.

The easiest way to recover the complete auto-zoom capability is to do a cold start, but you have to ajust them to fit your taste. They are other more cumbersome ways too.

I have been hoping that Garmin would have fixed the behavior through firmware updates...

Exactly!

Yes, this is exactly the kind of thing I've been talking about and I have noticed all the behavior you have described! At some point here soon I will investigate the files and see if I can find if zoom settings exist.

Another important feature removed

All of my previous nuvis remembered my zoom settings. My new nuvi 2598 does not.

Me too

That's my experience too.

I decided

I decided to finally see if I could locate any zoom information on the 3597. I can't seem to get to the System folder, though. Does anyone have any tips?
1) System files are not hidden
2) Hidden files unchecked
3) Typing manually into the .System folder does not work. It says it can't find it.
4) The Garmin XML document does state the .System folder should exist, but I can't seem to navigate to it or see it.

Any ideas?

MTP?

In addition to the computer's folder options, have you switched the 3597 from the defaukt MTP mode to MS mode?

Good info

Good info

Fixed?

So a curious thing happened after map update 2017.20. It seems that the zoom levels on my 3597 are now fixed and work normally! I have no idea why a new map would have fixed this.
My software version was already up to date, and my wife's GPS (3760) had normally working zoom levels the whole time.

Has anyone has who had this problem see it fixed with this map update?

Basically what Narvick said above. the settings are per individual preference.
