Also, take a look at this thread for a review and some discussion of that model.

What is the SD slot used for?

I don't know how far removed the 4040 unit is from yours but I have written an article below on your very question. Like I say, it may not apply to the 3225. Hope this helps you.
BTW, I am very pleased with the 4040, have traveled all over Ga. and Fl., about 1600 miles and it worked great and saved me in the Miami Beach mess.

The slot is for an SD card that you will need if you intend to backup the address book or download upgrade firmware or POI's you develop. I use a SanDisk Ultra-II 2GB in size.

it has 1gb memory in the unit.so with 1.3 million poi,it still has almost 800MB empty space.so lots to use.

Was wondering if you can add red light camera poi on these units?

My 3225 quit working yesterday after 6 days of use. It just would not turn on. I took it back and Costco gave me another one. Other than that, I really liked the features. I put custom POIs on it just fine.

Are you speaking of the Maestro series Magellan? If so, they will take the red light POI's by developing the POI in the POI editor that is on the disk packaged with your unit. You must convert coordinates to decimal equivalents and save as a Magellan file format. Then transfer the files to an SD card and place them into the gps.(the POI's reside on the SD card and not internally in the Magellan) Call up those files in the Magellan and set the alarm parameters and your off and running. I just recently set up my friends Magellan in Tucson AZ. with 30 POI red light cameras and we tested ten of them and they worked fine.

3225 was available briefly at Radioshack.com but now not any more. I think it is same unit as 3220 but with TTS capability. Red light camera alert in Enhanced POI should work.

You can find information to upgrade it at:

What?? First time I've heard that for the Maestro's.

I've loaded 2 files and haven't verified either yet to be sure they are on target but I've seen no mention of doing a conversion........either in the documentation or any of the forums.

My assumption is that the POI editor takes whichever format you give it and converts to what it needs for the unit.

You may be doing a lot of manual conversion for nothing.......or I might be wrong.

Yeah, I think it takes care of that for you.

Unfortunately the 4200 does not read from the SD card, it is only used for back-up or a firmware update. However the user can follow your directions and in the POI program click save to GPS - Making sure the GPS is attached by the USB cable, then find the GPS in the pull down list as such. MyComputer/TFAT/USR/CPOI
save the file to this directory and then you will find the option under Enhanced POI that is located in "points of interest" in the menu.

Mind you, I have found from much search on the web, that the 4200 is a bit different.

Final answer, I did get the camera red light working and alerting me !!!

If it works like the 4250, then it WILL read from the SD card, it just doesn't let you WRITE to it through the GPS because it doesn't show up on the computer as a drive.

I think you will find, however, that if you take the card out and put a POI file on it with an external card reader, in /USR/CPOI, that the unit will be able to find it when you put the card back in the 4200.

Of course, this doesn't help much of you don't have a card reader on your computer!!

That was my problem and I purchased a card reader that plugs into the USB port for under 10 bucks.
