Question about Magellan RoadMate 300 GPS Receiver

No maps found!!

Help!! Bought a used rm300 and upon starting, the unit is not finding any maps. I have both of the CD's but am not sure how to re-install the maps. I think the previous owner reformatted the memory hence losing all of the preinstalled map data. Any suggestions?

Re: 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.

For Garmin 255w, "No detailed maps found that support routing". How do I fix this?

You can not copy a map from one identical unit to another because each unit needs a unique map unlock code that is based upon the map id code and the units internal serial number. The code is a 25 digit number. If you can email us at sharcnet-usa at sharc dot net, we can help you resolve this problem.

I got a tomtom in us it has us maps on it bought europe mapping card it gives a code and says i need an activation code if you can help i have since bought another so need to get going with uk so i can get...

To obtain an activation code, the first thing you need to do is to find the product code of your TomTom product. This productcode can be found on one of these places:
  • on the 'productcode card' in your TomTom box;
  • in your CD jewel case, behind your CD;
  • in your CD box, behind CD 2;
  • on your My Account page (for Map downloads);
  • This product code consists of 3 groups of 5 characters and digits.
Need help? Check Where to find my product code?

Visit the TomTom support site if you lost your Productcode.

Garmin Nuvi 1450LMT, after entering a state, then attempting to "spell City" after entering city, and touching "done" unit indicates, "no matches found". For example, Minnesota, Minneapolis, unit...

Is the map turned on? At the main menu, press the system tools icon and press the map icon. Then press the map info button.

What does it say? Does a map show up and is there a checkmark in the box next to the map description? Also, if the map is for a certain area, say lower 49 states, SW, well you won't be able to find a city in the NE because the map is only showing a limited area. If you have ample memory on the unit or have a 2GB or larger SD card, installing the full US & Canada map is the way to go. Make sure the map installed on the unit covers where you are and where you may be going.

Hi I just bought Garmin 1490t and used it few times but couldnt find the option of turning on the lane assist mode. Can you please guide me how to use this function. Thanx Masaood Iqbal

I have the same GPS and the lane assist only works in areas that are available. For example on the NY thruway only the most popular exits show the lane assist. I was a little disappointed when I found this out, but hopefully that will add them on future map updates. Also make sure you register your unit and do all the software and map updates; maybe it may show more lane assist roads. Hope this was some help,Thanks for using FixYa

I have a garmin 260w that was a gift in dec 2009. I want to update the maps to the unit and thought there wasa n option at no charge but I cant find it. Do you have instructions on how to update unit for...

Sorry, no free maps. I know I've tried. You either live withthe old map or buy the latest version.
I bought the life time maps updates and I'm glad I did.
I've updated my maps at least 6 times.
New maps are about $70.
Life time maps are about $99 (when I bought mine)
BUT FIRST make SURE you have the latest software in YOUR computer and in YOURGarmin before you load any maps.
You can get that FREE at Garmin here:

To download the latest unit software visit Garmin website: First you have to set up an account at Garmin using theserial number on your GPS. Once you do that you can download firmware updatefor free. After installing WebUpdater once from the Garmin website,perform all future software updates from your computer. Simply connect yourcompatible Garmin device to your computer, then run WebUpdater from yourcomputer's "Start Menu" by selecting "Start","Programs", "Garmin", and finally "WebUpdater" REMEMBER: It takes hours to do a complete a mapupdate.
Unless you bought the Lifetime maps you may have to pay for current maps. By the way, thecorrect Garmin approved power OR download cables are a must!! Does this help? Let us know. Thanks.

Magellan Maestro 4250 2008/2009 Map Update will not update my GPS

I also had problems with a refurbished Magellan 4250. The paperwork inside said to install the 4.85 firmware update which I found would not work with Windows XP Home at least for me. I used my laptop which has Vista Ult 32 bit it updated with no problem that is so far the only solution I used.

You can upgrade the unit software for free. I think you are trying to update the installed maps, which isn't a free feature.

No maps found??

The problem is caused by a version mismatch between the Application version and the Map Version. They must both be the same. For example, if the TomTom has not had the application updated, but you updated the maps, the TomTom will not know how to read the file.

Make sure that if you are trying to use a version 815 map, that you are using a version 8.XXX application too. I had to upload two application version changes before I could read the new USA maps.
