Garmin 48 memory loss

Stored my Garmin 48 over the winter with weak rechargeable batteries. Probably, this depleted the memory backup battery, and the unit lost memory. Started my Garmin on fresh batteries, but was unable to initialize either via country or "autolocate" - just could not get any satellites in. (My older Garmin 45 worked in the same place) Checked the date of the Garmin 48 unit - it showed April 10 in mid May. Presumably it uses the Almanach of April now, no wonder it does not find the proper satellites. Is there any way to reset the internal date of the Garmin 48 to the proper value of today? Is there a "hard reset" that can do the job? Thanks for your help! Rolf

    Same problem on my Garmin 45. see my earlier posting.

    Dear Jon

    Thanks for your comment - our local Garmin agent did not impress me too much, he did not seem to know a solution. But there is one, if you can get hold of another Garmin 48 or 45 (that works properly!): Join the units with a Garmin-to-Garmin cable, and make the working unit send the almanach (Interface - Garmin/Garmin - Send ALM). This solved my problem, the defective 48 cold-started up again properly (takes a while) and did work ever since. Be careful not to mix the units up and accidentally "Send ALM" the other way, or you will lose both...

    Good luck and happy sailing

I have similar problem with Garmin 45 that has been in store and as yet no answers from the experts on this site, just suggestions to try the obvious or do things that are impossible wirth the unit in question. Same date problem in the unit. I think that the only solution will be to send the faulty unit back to the manufacturers via your local agent or store. Let me know how you get on.

Regards,

Jon.

    Hi Rolf,



    To date your comments/solution have been the only good advice that I've received. All I need now is a cable and hopefully the Garmin 45 that I have that works will sort the problem on the one that doesn't work.



    I've not seen the command anywhere on the menu to send the almanac. Hopefully if I connect the two units this might appear as an option. What do you think?



    best regards,



    Jon.

Battery will not charge


li-Ion batteries have a bad habit: whenever fully depleted, they lose a few cells, to the extent that they might not be able to hold a full charge if enough cells are damaged. In other words, repeatedly using a laptop (or any other Li-Ion powered device) to battery depletion can shorten the battery's life significantly. You might want to keep the batteries fully charged whenever possible and avoid fully depleting them too often.
There is also the habit of "re-setting" the batteries by using the "fully deplete-fully charge" procedure. It only applies to niMH or NiCD batteries ( and is used to erase the "memory effect" ) but is damaging to Li-Ion batteries for the reason mentioned above.
so if your battery can not full charge,this mean you need change a new battery for your laptop

Would you like to back up a copy of your Garmin Nuvi 205W Favorites and Waypoints?

Backup and Restoration Procedure for Favorites:

  1. From the Nuvi drive, copy '/Garmin/GPX/current.gpx' to a backup location on your computer.
  2. After a hard reset or loss of data, copy your backed up 'current.gpx' from your computer back to the '/Garmin/GPX/' folder on the Nuvi, but be sure to rename it 'temp.gpx'.
  3. On the next power cycle, the Favorites will be read from 'temp.gpx' into the non-user accessible memory area on the Nuvi where they are actually stored.
I hope that helps.

Your battery has probably just reached the end of it's service life, or developed a memory after repeated chargeings without being fully depleted. All rechargeable batteries have an average maximum number of duty cycles. (drain and charge) If your charger has a deep cycle feature, try using this to completely drain and recharge the battery. If it doesn't, try putting it in your trimmer and locking the trigger back for a few hours, then recharge it. If neither of these work, it's time for a new battery. If you do get a new battery, be sure to COMPLETELY drain the battery before recharging by locking the trigger back every few uses to avoid developing a memory and help extend the life of your new battery.

Won't start after winter in garage with fuel stabiliser


your battery is dead. The electric clicking is a telltale sign that the battery is weak or depleted and does not have enough juice to turn over the starter. This is extremely common when the car is left to sit for an extended period without being used.

the clicking you hear is the starter solenoid trying to engage the starter, but the battery is to weak to do so.

There are a couple solutions. First you can get a set of jumper cables and jump the s2000 with anther battery. Once the car is running the battery will alutomatically begin to recharge.

the second is to buy and use whats called a trickle charger or 'battery tenderizer' this is a small device that you plug into the car and it will automatically keep the battery charged over extended periods of time without the risk of over charging the battery. If you use one of these it will also slowly charge yoru current battery enough overnight for it to work in the morning.

GPS 48 MEMORY LOSE


You can go to batteries plus or wherever and buy a new 3 volt battery for it. You will have to unsoder the old one and soder the new one back in. Original was a VL1220, I replaced with a Dantona Lith 1-2VLS

Unit fails to maintain charge


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.

Garmin GPS 45


It is probably one of the following:
1)Old Software
In 1999 the GPS satellites were reset and the new almanac data had to be loaded into the GPS 45 for it to continue to work. It was not uncommon for that model to quicly kill a set of batteries when it is having difficulty acquiring, which would cause it to shut down in order to save the batteries for its internal memory.

I just did a quick search of the Garmin website and it appears they no longer support that model. If you go to their support page and send a request for a software update they can probably e mail it to you. The update is free but to down load it, you need a PC interface cable (RS232 serial port connector) Part Number: 010-10141-00 Suggested Retail Price: $ 38.09.

2)Bad antenna
To rule this one out, borrow an antenna from another Garmin 45 or Garmin 48, or plug the unit into an external antenna and see if the unit still shuts down. The drawback to this method is that you can buy a new GPS that is superior to the one you have for about the same price as an external antenna.

3)Bad batteries
If your batteries are low, the unit will automatically shut off to protect its internal memory. I tried a lot of different batteries in my 45 and I found that Eveready alkaline batteries worked best. Rechargeable nicad batteries don't work very well because they fool the battery meter. Newer models have a setting to specify that you are using rechargeable batteries.

Ultimately the best advice I can give you is buy a new GPS. For less than $150 you can buy a new model that is more accurate, more reliable, stores more waypoints, has a better display, is easier to use, and gives you more valuable information.

Please rate this information as helpful.

Loss of memory


The back up battery always shows 100%, as far as my experience shows. The backup battery is only utilized to retain memory while the main battery is dead. The backup battery charges first, so if the ppc has enough juice to be turned on, the backup battery should be at 100%, unless it is plugged in and you are just now turning it back on. Even so, it will probably still show 100%.

Basically, you left it on too long and all the batteries died. Sorry, but your data is gone :-(

Loss of data when battery goes dead?


-are all pda's this way? All PocketPCs are this way. I don't own a P**m so I can't speak to them. -When the main battery depletes to the point where the unit shuts off how long do you have before data is lost? Until the backup battery dies. -Is the backup battery just used when changing main batteries or does it take over when the main battery goes dead? If so how long do you have before it is dead? I've never had it happen, so I cannot say how long, but if you continue to try to use the PDA on the backup battery it won't be long (minutes) if it even lets you do that. The backup is there to bridge over battery changes and to act as a safety net if you run the main batteries totally flat. -does the backup battery recharge or does it have to be replaced? Replace. -with a fully charged unit how long can it be left off before data is lost? Depends on the machine. Most of us leave the thing in the charger overnight every night, so this issue doesn't come up. You could try an experiment for 1, 2, 3 days, looking each day at the battery remaining and work up an estimate. I would expect maybe a week or more. Remember, even "off" the machine is still drawing power to maintain the RAM memory.

"Upload ...Not Present" message. Nothing else on the screen. I replaced the internal battery last spring used it all summer. Have just checked internal and external batteries and all are fresh 3v internal and new AA four batteries. Upon startup the screen says "Upload" "Not Present" and there is no menu. I have tried hitting Page and Menu, etc. nothing happens. I tried leaving it out and on for 3 hours to see if it would find itself and satellites. I tried connecting to the computer and uploading the internal program the port was not found. Tried this a number of times and a number of ways. I have tried leaving it on to search for 3 hours and have tried to connect to my computer to reinstall the software but that does not work. The internal battery was replaced with a new one last year. I have fresh batteries in the unit. What is the problem? How do I fix it? Thank you. I love this unit and would like to keep it going. I have fixed two others for friends who needed the internal battery fixed. They use it as a backup. I have tried the Auto Locate procedure about 3 times. I have also tried clearing by holding the PAGE + Power. Then tried autolocate. Message "Upload... Not Present" still remains. Also have tried clearing by holding the MARK + Power. Then tried autolocate. Message "Upload... Not Present" still remains. Now I am wondering if this message has to do with an interrupted connection with EasyGPS from last winter. I was uploading waypoints, and thought it had completed and may have turned off and disconnected the plug before an operation was completed in saving waypoints off the Garmin 48. I do not know this for a fact, but that was the last operation I recall doing last fall, before starting the GPS up again on the boat this spring. I have also tried to connect the unit to Easy GPS via the serial port, thinking perhaps it would complete whatever it is trying to do. I have tried uploading routes and downloading routes via EasyGPS send and recieve and it does not seem to work. I wonder now if the interface setting has been reset, by my pressing PAGE+power and Mark + Power earlier. I would not mind that if the menus came up properly, but that is not happening. Is there some other way to kick it out of this mode? I turn it on and there is the message "Upload...Not present" and none of the menu buttons work to get it into the normal startup screen mode..... I've tried Quit, Page, Enter, Goto, Mark, Power (off and on), and none of the get the computer out of this mode and back into the normal menus for startup. I've removed the antennae and checked all the contacts and that seems fine, and reinstalled. Is there some small reboot button inside that I can jumper? I have tried taking the internal battery out and letting it sit for three days and it still does the same thing. Any suggestions would be appreciated
