Re: magellan 300

You have to contact magellan. They will e-mail you an index file. You have to hook up your GPS to the computer. Then cut and paste the file onto the GPS hardirve.

SD Card for magellan 300,Can I use any card on it? I've just got it as a gift without the card. Is there any website where to buy it?

The Magellan Roadmate 300 and 300R both require preloaded map data to be supplied from an SD card. You can't just pop any card into the slot and get it working. It requires a card of 2GB or less loaded with Magellan mapping software. Magellan provides nationwide maps and regional maps. The 300R was a regional unit while the 300 included a national basemap.

If you have a model 300, you can still use the highway basemap to get routing from city to city but you will not have detailed address routing at the residential street level unless you insert an SD card with Magellan software. If you have a 300R model, the unit will be useless without the Magellan software on an SD card.

Magellan doesn't seem to offer much software support for this unit any more and the maps are difficult to find.

When I power up the roadmate 300 says there are not maps....the drive shows that they are there ? when I connected to computer with disk asked for authorization code.....would not let me enter one...called...

Unfortunately the authorization code comes from Magellan so there is no way for us as end users to bypass it. I would call back to Magellan and ask to speak to a supervisor or manager. Someone there has to be able to provide the authorization codes, tell them you have a very popular blog and plan to let everyone know just how horrible Magellan's customer service is unless they help you. It is ridiculous that they would be holding you hostage essentially like this. I wish I could provide you with the authorization codes but unfortunately it is tied to the unique identifier from your magellan unit, and the serial number of the map software, both things that Magellan can easily check, and then provide you with the code.

I would keep calling until someone gives it to you, that is simply not acceptable.

So sorry to be the bearer of bad news, but noone on here will be able to give you those codes, it is a manufacturer dependent thing.

Good luck, sometimes it just takes a little persistence, and like I said, make sure you are talking with at least a level one supervisor.

Missing SD Map Card on Magellan Roadmate 1212

Unfortunately even if you do find a card it will not work with your unit because the cards have to be for that unit.If it is from another unit the codes will not allow it to work. The only option I know of is to purchase your map for that unit and put it on a sd card

Loading New Map

I don't know if this is much of a solution, but from what I understand from my extensive research on this product (I bought one online and have been trying to get updated maps), Magellan no longer supports this unit. I looked on their website to confirm, and on the "Scheduled Map Updates" list, the Magellan 300 has no further updates available. Apparently, this has been the case for the last few years.

My new Magellan Roadmate 300

You have to have the two cds that come with the unit to download onto your computer. If you can find these then there is a sd slot on the bottom of the unit covered by a small rubber cap .The sd cards must be the ones that will work on a magallen .You can go to magallens internet site and get a list of the ones that will work.

No maps found!!

Hi - I have the same model GPS but I've been unable to locate a copy of the CDs and I'd love to get a copy of them - would that be possible? My email address is

As far as re-installing he maps, here's what I've found. I think this might help:
Locate the files that are loaded on the computer.Magellan Roadmate Manager example: C:\Program Files\Magellan\Magellan RoadMate Manager NA\Map\Basemaps
Copy all files. Make sure your Roadmate is connected and click on Example E:/Removable Disk and paste them with other files. It takes a few seconds to 1 minute to transfer the 25.5 mb file so don't unplug it until it is finished.
