Question about Garmin Forerunner 305 GPS Receiver

2 Answers

Will not power up out of cradle

Unit indicates charging battery while in cradle for aobut 3 to 5 seconds. Than indicates fully charged batery. Take the unit off the cradel and it goes dead.
Per all of the other solutions I've seen, I've downloaded all the updates, tried all of the resets.
Ordered a new battery for the unit. however, can't seem to find an easy way to take the unit apart to install the new battery.
2 questions:
Anyone know the easiest way to replace the battery at home?(No it is not the HRM)
Or
Should I send it in to Garmin for them to rebuild for the $100 cost?

Unit is out of warranty.

Thanks

To power the unit back on, press the "Mode" and "Reset" buttons at the same time. Let go of those two buttons, press the power button, and the unit will turn back on."

I had exactly the same symptoms..

A bit after your post but here's my experience….

Opening it up:
The plastic base has a rubber facing on the outside (surrounding the side buttons), but as far as I can tell it is a plastic-plastic interface that glued to unite the top-bottom with cement. As has been said elsewhere, there are no catches to worry about…

Run a thin but blunt screwdriver or knife around between the “rubber” surround on the base and the top (black) plastic, applying slight lever pressure as you go (be careful and you won’t dent the plastic).

Turn the unit over so the top face is down and the contacts away from you. Apply a gentle pull on the strap nearest you while levering with your fingers at the bend in the base…this should (or did with mine) allow the base to separate from the top.

Now it turned out there had clearl;y been water ingress in my unit, between top and bottom above the contacts, one in particular at the end had corroded significantly…and on using contact cleaner carefully there was no gold left on the worst one and the mating contact on the circuit board simply fell away….. Bugger!!.. that’s basicly screwed any plans for my self-repair as can’t solder between the 2 with nothing to bite one….

However, it's not all about me!!!..

If your issue is the battery itself and you want to replace, here’s what I found…

Battery is marked as follows:

“Garmin part 361-00026-00
3.7V Li-ion 750mAh”

But (of course!) Garmin has not designed this for self-service (or by the looks of things for ease of service by anyone, given amount of glue used!), so that part # is not for sale…

Anyway, the actual dimensions of the are approx H 33.5mm x W35.0mm xD 5.5mm

..so the Ipod 4G battery, although rated the same, would actually be too big to fit (being 46*32*4.5mm)

I haven’t done an extensive check (not needing a new battery now!) but you may be able to source something very similar (possibly slightly higher capacity?) from something that suits (Canon?) cameras or a PDA device?

To change you have to lever out the old battery (its fairly securely glued to the base) then sever the leads from the existing battery and reconnect to your new one…would need a steady hand and preferably aWill not power up out of cradle - 4927918.jpg glass!
4927918.jpg
Putting it back together….It fits really snugly…Just clean off old glue carefully by scraping, replace with a glue that suits plastic-plastic and won’t destroy rubber and all should be sweet….

Good luck!

    Oops, meant to put at the beginning...

    No liability accepted, but thought I would relay my experience and it may help someone!!





    My unit stopped charging (suddenly) – had been brilliant for 14 months, holding charge for 12-13 hours). Figured it was a battery connection issue. Unfortunately I have a key race in 2 weeks, love the device (when it’s working) and find it very important to pacing (ultras)…but Garmin support sucks bigtime (not even a response to emailed pleas), so figured I may need to buy another to get one in time anyway and had nothing to lose by attempting to have a go myself…

    Cheers

The unit turns on and off every 1 minute (while charging) is there a way to avoid it this restart?


If this is happening while driving, you could have a cradle going out. Try moving the plug at cradle slightly and if it indicates battery then charges, your cradle is defective. Cradles can be found cheap at www.gpsnstuff.com.

Show charging symbols


Your question was posted under the Nuvi 680 GPS, so I am assuming this is the model that you have.

On the main screen, you will see a green battery status indicator in the upper right-hand corner of the screen. The battery is divided into 4 parts. Each part represents 1/4 power. So if you have one green bar, that indicates that the battery has 1/4 of power left. If there are 3 bars, that indicates that there is 3/4 power left.

When the unit is charging, you will see a yellow lightning bolt appear over the green battery status icon.

When the lightning bolt is not there, this means the unit is running off of the battery.

When leaving the unit to charge, press and hold the power button until you see that the screen says Charging Battery. A few seconds later, the screen will go blank to save energy.

Pressing the screen again later will either say Charging Battery or Battery Charge Complete.

My sky caddie sg5 wont charge


If you follow these instructions which I think you know how to, it will recharge. If not the rechargeable battery needs to be replaced

To charge the battery, simply follow the steps below:
  1. Gently pull back the rubber cover to gain access to the mini-USB port located at the bottom of the SkyCaddie. Insert the mini-USB connector of the supplied wall charger into the mini-USB slot.
  2. Plug the wall charger into the AC wall outlet. While charging, the charging indicator in the upper left-hand side of the SkyCaddie will show red. The charging indicator will switch to green when fully charged. You may also notice the unit's screen turn on and off periodically.
The battery will charge, even with the SkyCaddie turned off. A full battery charge may take 4 hours. Once fully charged, expect 36 holes of continuous play.


Warning!Always connect the cable to the SkyCaddie first before connecting to AC power or PC USB.

Garmin 305 wont power on, wont charge on cradle


Same thing happened to mine. Put the unit in the cradle (just like you are going to recharge it) and press the reset and mode button at the same time for 3 seconds. This will "wake" the unit up.

Battery Charging, Nuvi 35


Charge the unit over night, Plug in the AC charger and you should see a lightning bolt over the battery bar graph display.

With the charger plugged in, gently press and hold the on/off power until the screen goes black and displays the text "Charging battery". After a few seconds, the screen will go black to conserve power. At any time, you can press the screen and it will light up saying its still charging.

If you let it go over night, when you touch the screen, it will say Charging Complete and you can then remove the charger. You should have full green bars on the battery indicator.

Sounds like you both have a battery problem. I experienced a similar problem when trying to charge via the USB-cable connected to my computer.
Ended up buying an original charger (expensive) and the charging went smooth.
The car charger should in any case work fine, so probably your battery is not very healthy.

Try holding your finger on the battery symbol for about 10 sec. The unit will then switch to a technical page. There you can observe the battery and charging voltage. When I plug in my computer USB-cable, I read around 4,4V and that is not sufficient for charging my battery.
When connected to the original charger, this voltage rises to about 5V which gives a nice charge. When unplugging charger, the unit displays the battery capacity. If the charging voltage is OK, but battery capacity drops quickly after you unplug charger cable, the battery is probably bad. (Of course you have to charge is for some time) I think around 4V battery voltage give 100% capacity. 3,9V gives about 90% capacity.
This will not solve your problem, but can give you an idea about what is wrong.
Good luck.

Zumo not accepting a 12v charge


Mike,

My friend had the same issue as you mention. Puts his Zumo 550 on his bike only to have it discharge in a few hours. He later found out the pins on his motorcycle cradle had corroded and therefore was not keeping the Zumo charged. His solution was to purchase a new motorcycle cradle at about $100.00 CDN.

Garmin c340 does not charge


I came here looking for solution and tried the "press eraser in bottom right corner and turn on" but didn't work for mine BUT if you look at the face plate (the part on the front that says "Garmin",) just under the word "Garmin" you see a small indent in the plastic, useing your finger nail, gently pull upwards and the face plate will come up. Also, be gentle while pulling the face plate being careful not to break it. ( I advise that you use your nail and not anythng that might scratch the plastic if you are intending on returning the unit, cause they may suggest that you tampered with it and that "voids the warrenty") Anyway, look at the USB plug (above the ON button on the side) and you see a tab, press it and the unit will reset.

Seems to me that with all the problems Garmin has had with their units freezing up that I should have found this solution on the garmin site! To think that there are people who will throw there unit away because of this problem OR who will pay 150.00 bucks to get it fixed through Garmin.

Internal battery won't charge


Common issue. Steps to troubleshoot/solve:
1. Pull off face, press reset tab.
2. If unit wont turn on or if turns off immediately, connect to home computer using mini usb on side of gps (any usb cord that fits will do). This will charge the internal gps battery, which is discharged.
3. You will not be able to see the gps charge indicator while the usb cord is plugged into the unit. To check charge level, disconnect it, turn it on, and note the large "battery" icon.
4 Do you have a dead internal battery? If the gps holds a charge from your computer usb port, you don't.
5. If you have a dead battery, Google DIY replacement. With some soldering it can done for $15 total.
6. If you don't have a dead battery, the issue is charging from the cigarette lighter socket. Your car socket may have blown a fuse (check car manual). Your charger unit may have blown a fuse (unscrew the tip, check fuse inside). Also, some car sockets don't work when the ignition is off. Test yours.
7. There is a good chance the connection of the charger wire to the gps cradle is the problem. Fiddle with that. Replacement cradles are available for the c340 at about $25.
8. If your unit is not charging from the cradle/socket, buy a 12v usb cord. Plug into socket and into usb port of the gps. This is a workaround or alternative to buying a new cradle.
9. IMPORTANT: observe the "battery" icon while driving, esp. if you have doubts about charging. Basically, if you can see the icon, you're not connected to an outside (car or computer) power source. That is, if you can see the battery-charge indication, it means your battery is currently discharging and unless you get another power source to work it will be dead in a few hours.
