Nuvi 2595 not functioning properly anymore

 

I've had this 2595 for a couple of years now and this past week it became unusable. It turns on and appears to function, but if I select an address and try to start a route it bogs down and becomes very unresponsive. After hitting the Go button, it takes a while (maybe a minute) to switch to the map view. Then once there, the calculation will very slowly increment but never seems to finish. The last time I tried it once it reached 80% it stayed on that value and never came up with a route. Meanwhile I could see the map below updating as the vehicle actually moved.

I've tried giving it a hard reset and it didn't seem to improve at all. I've updated it with all the latest software and map updates. Again no improvement.

Is there some sort of diagnostic that can be run to see if the internal memory is bad and/or files are corrupt?

.

Sounds like the symptoms of the unit's internal memory being full.

Go through the device and delete unnecessary files and also clear the trip log.

See this topic for details (note that it's written to free up space for maps but this also applies to free up space on the unit in general as well).

I agree. I've bricked one that way.

Thanks for the

Thanks for the suggestions.

When I did a hard reset to the nuvi, it cleared the trip log and other user data.

I followed the instructions and made a backup of the device files. Before deleting anything, I wanted to ask is there a certain amount or percentage of free space needed for it to operate correctly?

Currently it is showing 7.2 GB total space and 1.46 GB of free space. Does that indicate that there is a free space problem?

That. ..

... should be ample. If you've tried a master reset and you have that amount of free space I'm surprised you have an issue.

That's what led me to me

That's what led me to me original question - is there any internal diagnostic tests that can be run?

Now that I have it in Mass Storage mode, I was able to use Window's Tools to check for errors. It detected nothing wrong with the Nuvi file system, so that doesn't seem to help.

Just a thought

Have you recently added a lot of trips to your unit?
I did that to my 2450 and it bogged the unit down because it was always trying to load the maps.

Thanks for the response. I'm not sure I understand the question though about "adding a lot of trips".

When the problem first started happening, it still had the US map from last year. That's the last time I had updated it and things had been stable up until last week.

When it started going wacky, I think I tried updating the map to this year's version (I don't think there was any other software update available so that didn't change). Map update didn't help. I did a hard reset to the unit that removed all user data, trip logs, etc. Still didn't help. The thing still sort of works while using the menus but once you try to pick an address and use it, it behaves erratically and is unusable.

A Possibility

On some newer Nuvi's, including my 3597, if you press and hold the battery icon in the upper right corner of the screen for 10 seconds, the unit goes into diagnostic mode. On the 3597, there are tests for internal RAM and ROM along with statistics and a host of other tests.

Since I don't have a 2595 to test, I have no idea if this will work for you or not. It's worth a try though.

If you do manage to access the diagnostic screen, be very careful about what you change. You may further cripple the unit.

Hi thanks for this info. I am able to get into this diagnostic mode. On the first screen at the top of the second column I do see:

RAM Test Ready
ROM Test Ready

Not sure what that is trying to tell me. Already passed the test or ready to start??

Hitting the Next button takes me through Audio, Bluetooth, RGB-type tests. Eventually I got to a screen that has "Start Chksums" and "Start Test" buttons.

I clicked on Start Chksums and after a several minute wait it calculated checksum values for Voice, ASR Language, ASR Map, and ASR Map Dir. Perhaps we need to know what the right values are supposed to be there to see if there is an error, not sure.

I next tried Start Test and that very quickly came back and enabled the More button. Several things are listed as Pass and more checksums. If there is a way to attach images to this forum, I could put the results here.

Unfortunately I don't see anything that is an obvious smoking gun from this info.

A little more info

I found there is another diagnostic menu I can access by selecting the speed in the Map view and then pressing and holding on the speed value on the next screen.

There is a Shutdown Causes item on this menu. This morning I tried the Nuvi again while out driving. It sort of worked for a small bit and then eventually rebooted itself. This menu lists:

Data Abort
08:09:39 AM

Pressing on that yields a trace dump. I suppose only a Garmin Level 3 support person would be able to interpret what actually failed.

I was talking about routes.

I call routes trips. It sounds like you didn't do any of this.
Did you trying connection to Garmin and reinstalling the maps just in case the maps are corrupt?

Some questions

In your original post you mentioned the delay and failure when searching for an address.

1) Your current map is for all of North America, right?

2) How far away from your current location is the destination? The destination is in the coverage area of your installed map, right? Finding an address and creating a route in your city is a lot easier to create than one 1500 miles from your current location.

3) Have you tried searching for a place (restaurant/motel/city/etc.) rather than an address and if so, does it succeed? Addresses can be tricky because sometimes you enter 2181 Generic Pike as an address, for example, while the map thinks that location is 2181 State Route 57, etc. As a test, have you tried to create a route to different addresses, near and far, or have you only tried the one address that's causing a failure. In a later post, it seems you did mention that you could create routes to destinations using the menus but failed only when the destination is an address.

4) Before starting the search, your nuvi has a good satellite lock on your current position, right?

So last night I tried deleting some of the extra language files, turned the nuvi back on and made sure it was still functioning, then tried your idea of reinstalling the North America map. Unfortunately it still has the same symptoms - any time that it goes to the Map view, there is a long delay before it ever displays the map and then it behaves erratically.

Thanks for the response.

I was testing with addresses that were just a few miles away. The Nuvi responded just fine in finding addresses, it's when I hit the Go button and it should be going to the map view there is a long delay before the map is ever shown and then erratic behavior.

I tried a restaurant that is less than 2 miles from my house. Same behavior. There is always a long delay switching to the map view. Sometimes it will then act like it's going to work (turn by turn directions start), other times it never finishes calculating the route. The times that it does actually start to work after the long delay, it is only a matter of time before it begins to act erratically (screen doesn't keep up, turn by turn audio stops, unit reboots, etc).

As far as I can tell it does after I reboot it. Is there something in the menus that I should be checking to make sure the satellite function is good?

Satellites

The satellite signal status icon is at the top of the main screen. It has several green bars.
---------------------
From the 2595 manual -
Satellite Signals
After the device is turned on, it begins acquiring satellite signals. The device may need a clear view of the sky to acquire satellite signals. When at least one of the bars is green, your device has acquired satellite signals.

Viewing GPS Signal Status - Hold the green bar icon for three seconds.
---------------------
The GPS cannot see the satellites if it is inside a building. If it doesn't know where it is, it cannot navigate or create a route.

The nuvi should have several green bars, not just one. If not, turn it on and place it outside in an open area without moving it around, for as long as it takes to get green bars - up to 20 minutes.

Did you have to install your map to an sd card

If so was it the first time to install to a sd card? If so was it one of the newer cards, at least a class 10?

Trafffic trends?

Have you disabled Traffic Trends and My Trends? If not, try that and see if it makes a difference.

Yep I got green bars.

This nuvi is running on internal memory only, no SD card involved.

Traffic

trafficTrends is not enabled according to the Traffic menu.

I can't seem to find My Trends. Searching through the PDF manual doesn't seem to indicate that feature is there.

You won't

The 2595 doesn't have myTrends
