3590 Connection Issues

 

I have 2 3590LMT's. My older one (a refurb unit) has issues with powering up about 20-25% of the time with a white screen. Unplugging it and waiting for it to power off generally allows it to start normally. It also has issues dropping audio level randomly and sometimes a stutter in the speech (usually when approaching a turn so that the instructions cannot be understood!!).

I purchased another 3590 (used) and it seems to be working well EXCEPT, it will not maintain power using the mounting bracket. It works fine, then drops power. Hitting it or removing it from the mount 4-5 times usually restores the power for a while, then it disconnects again. I noted the stuttering once when it lost power, so I am assuming that these issues are related to the connector.

I replaced the mount and am having the same issues. I have cleaned the contacts on the 3590. Has anyone else experienced this? I have not tried the older unit with the new mounting bracket yet to see if it still has the audio issues.

I'm beginning to think that the 3590 is a problem unit. None of my other Garmins has ever had any similar issues, and I go back to the StreetPilot!

Any suggestions are appreciated.

Thanks

3590 Connection Issues

Some additional info... I just tried connecting the 3590 to a USB cable on a power brick. It powers up the unit which is sitting on my desk. After 10-20 minutes, it loses power. The unit has not been touched or moved. Wiggling it in the cradle restores power (this is a brand new cradle).

3590 power issues

Sorry to hear about your 3590 problems. Mine has worked well for over 2 years now with none of the issues you discussed. Have you tried going from your USB port right into the micro USB connector bypassing the cradle entirely? That might shed a little more light on the power problem. Installing a new battery might be a relatively inexpensive option to try as well. You never mentioned doing a hard reset. I would do that for sure on both units. Also if you can do it, compare the file structure between the two units which might add some useful info. Hope these help.

3590 Power Issues

I have tried the micro USB connector at home (not in the car) and it does work. The issue that seems strange is that when in the cradle, sitting on my desk, it just disconnects. It's almost as if when the battery gets fully charged it disconnects from power, then wants to shut down.

Power up the unit as best you can. When you get to the main screen which shows the "Where to? and View map", place your thumb in the upper right hand corner for about 15 seconds or so and a screen full of data should pop up. Of the many things listed, you can see the battery voltage which just read 3.8 volts on my unit. Battery capacity is shown also. That might give you a clue about the state of your battery. Hit "Exit" to get out of this screen. Hope this helps.

erase contacts

If your cradle or what fits there has any bare metal contacts, it might help to scrub them with a pencil eraser.

3590 Power Problems

The Ogre: I checked the battery voltage as you suggested. It is 3.86V.

Greg: I will try cleaning the contacts. I was thinking that the seller may have used some type of cleaner on the unit to make it look like new and coated the contacts... The strange thing is that it just disconnects from power while sitting on my desk - nothing touches it.

3590 Connection Issues

After several days of emails to Garmin support (very frustrating), I am convinced that purchasing a used/refurbished 3590 is a big mistake. This is my second defective one. I could have purchased a new one for not much more.

Garmin asked questions a few at a time (one response per day)
Day 1. Serial Number. I had mistakenly read an 8 as a B originally
Day 2. Does the red light on the cable illuminate/Do I see a lightning bolt over the battery icon/Does the USB port on the cradle appear to be loose/Are you using the Garmin brand power cable.

Day 3. Today I got this message: "I suspect that the USB port on the back of the device is failing and losing connection with your computer and sometimes your car charger. Eventually, you'll need to replace that device."

Great assistance, Garmin.

My first refurb unit has sound issues and many times powers up with a white screen. This second unit will not maintain power.

I guess that you get what you pay for and a used/refurbished Garmin is a piece of crap.

If anyone has any suggestions, I would appreciate it. When it loses power the diagnostic screen says that the cradle is not present.

Contacts

I noticed what appeared to be clear varnish over the tiny contacts at the bottom of my 3590 refurb. I would scrape yours again, make sure the cradle contacts are all properly sticking out and springing free and the surface is clean.

Those tiny contacts can cause lots of problems. I used a magnifying glass to see the problem on mine. (It has now been problem free for over a year.)

If there is even the slightest debris or even uneven plastic on the bottom on the GPS, it can cause loss of contact, and mine seemed to do exactly the same thing that your second one did.

3590

I have a 3590 and I too have random shut down and often it will not power up when power is turned on. I have to use the power button.

The Bluetooth has to be turned off and then back on once in a while for it to sync to my phone.

It's not the most stable Garmin unit I have had.. for sure.

But I DO like that it shows the upcoming street names when not following a route.

UPDATE: I returned the 3590 that I had purchased (it cost about $90 on eBay) and purchased a refurb from GPS City ($150). The "new" unit appears to be working fine. Maintains power in the cradle, sound seems fine. Hopefully it will continue to work well. As a bonus, I now have a couple of extra suction cup mounts and 2 traffic cables (one from my original 3590), so I can keep one set in each car rather than moving them from car to car.

Thanks for all of the help and assistance in working this out. This was my first purchase from GPS City and they provided great service.

Just an FYI...when contacting Garmin with support issues, it's always better to call thnn to do the email run-around. Getting through when calling would take 30 minutes or so (depending on when you call) but the issue will get resolved much quicker.
