Unit fails to maintain charge

Unit will not re-charge from the cig.lighter. I changed the fuse and still the same results. Could it be that the battery needs to be replaced? If this is the potential solution, will I be able to change the depleted battery myself.

You are correct, most GPS units use a lithium ion rechargable battery, typically they loose there ability to retain a charge after about a year or so depending on use, resulting in the unit having to be always plugged in.

You probably could replace the battery on your own if you could get one, (needs to be soldered into the mainboard) however GARMIN does not sell battery's to consumers, they state that a battery can only be replaced by a garmin service tech.

Check the link below for contact info for garmin.

Hope this helps

It keeps shutting off

I would take a volt meter and make sure the voltage from the lighter plug is present where it enters the unit---the cig plug also has a fuse in it--no voltage would mean the battery not getting charged--those are good battery's and should last for years.

Magellan has fairly good customer service and may be able to help--rule out the no voltage reaching the unit for charging first--check the socket first and then the out to the unit second.

Blew fuse in auto cig. lighter, battery ran down in 255w. trus to power up and load but just double beeps every few seconds? thanks Ron

plug something else into the lighter to make sure its getting power, if it is then let it charge for awhile with the car running. if it still doesn't work try doing a reset. There is a reset button under the sticker at the bottom of the unit. it is located directly under the check mark on the sticker. hope this works. :)

Am holidaying in spain, have hired a c max and do not think the 12v lighter supply is working so sat Nav wont recharge. is there a switch or key position i'm missing as have not driven a c max previously....

Hi, their is no switch or key to get it working, on this car it should start working as soon as you turn the ignition on so as your driving it should be charging.

the only reasons it may not be working could be a fuse or some one may have shorted it out by leaving the cig lighter down to long.

have a look in the glove box and see if the owners handbook is in their if it is have a look in their at the fuse box diagram and locate the fuse for the aux cig lighter then check if the fuse has blown, if it has blown their should be a spare fuse in the fuse box and it should tell you this in the owners handbook,
if how ever the fuse is ok then this means some one has shorted the lighter out and the only way of getting it working is to get the main part replaced and as this is higher car its something you wont be doing.

i would check the fuse and if its blown put the spare in or if their is no spare then it would be worth buying one as they cost next to nothing to buy.

let me know how you get on or if you need further assistance ok

Battery losing charge whilst plugged in to cig lighter

I have the same problem, when the battery goes dead, it seems to do so instantly vs. just holding the charge for less time. You can replace the battery, but with the prices coming down and the fact that the map upgrades cost what they do, I'm thinking it's more cost effective to just buy a new GPS.

My garmin does not operate plugged in to my car nor by battery

You have not said why that is....

Have you fully charged the battery prior to using in the car?

Using the power from the 12v plug in a vehicle will not "charge" the internal battery, but tends to maintain it somewhat. If the fuse in the end of the 12v connector plug is blown and the battery in the unit is low then this will cause the unit to shut down or fail to fire up.

Please check both, the units battery level and the fuse in the cig lighter plug and the plug that connects the unit to the cig lighter outlet.

Now the second half of your statement:

Nor by my battery

It is either not charged ( AC charger) or it has reached the end of its life which if used correctly is about 2 years. If the life of battery is shortened , then it is by a common practice of misuse. This misuse is to have the unit plugged to the car 12v when staring the engine.

1) it damages the battery life
2) It can and does damage the SIIRF chip, which is responsible for connecting to the satellites

I suggest that if it does not charge over a 10 hours Max period to its full state, then replace the battery immediately to avoid damage to the electronics from battery leak.
Thanks for using FIXYA

Garmin will not charge using car charger. The fuse is intact. It will charge using usb port per computer. Any ideas?

meter out the cable and see if you are getting anything out of the car charger, of course while the car is running. If you are getting no juice, then either the fuse for the cig lighter is bad or the car adapter is bad. either way, easy fix. Good luck!
