Question about Garmin StreetPilot C330 GPS Receiver

3 Answers

I am trying to load the 2008 map update to my c330 unit but nothing happens. I get a no active connection error when using the dvd and from mapsouce I get a no memory error when it is supposed to save over the current version. When downloading version 5.70 from the web site but it tells me there are no new updates. The unit is still loaded for version 4.40 and map nt v8. Garmin support has not solved my problem to date. I would like to update this map before the 2009 version comes out. What am I doing wrong?

Re: I am trying to load the 2008 map update to my c330...

First, some questions:

A. Is the unit turned on and plugged in via the USB?
B. Is the USB connection active?
C. Have you downloaded the USB drivers to the machine you are using?

You can only load one region on the C330. It will not hold the entire update. That is why you are having problems loading it via Mapsource. There is a way to load the second region onto and SD card for use, though.

Perhaps your are using a low speed USB port. I once use the low speed USB and does not work. This unit only works in high speed USB. Hope this will help.

I have a street pilot C330 Garmin - I am trying to update with the latest maps, etc - but I am confused on how to do this. Please help - I am very happy with this Model and mostly because it is user...

Register your Garmin at - from here Garmin guides you to download the webbrowser plugin to communicate with your Garmin StreetPilot C330 over a USB cable.

When your Garmin StreetPilot C330 is connected through your webbrowser - it will show compatible map updates. These can be ordered on DVD or downloaded.

Note that downloading the map update will take a very long time and requires at least 5 Gb of disk space on your PC/Mac. The internet connection needs to be fast and stable enough to complete the huge download. Otherwise its better to order the update through DVD.

Free map updates for Garmin c330

Garmin has released new maps. Most of their units are entitled to a free update if the unit was purchased recently Just a heads up to anyone who recently purchased a C330. According to Garmin's tech support, the map udate 2008 is not free to those of us that recently purchased a C330. Only to those who purchased a C340 and up. Their excuse is that it is a "low end" unit, and also that the memory cannot hold the full US maps on the DVD. Gee, I can purchase the update for $69.99 and load a subset of the maps if I want, according to the person in tech support, but I cannot receive it as a free update. So, apparently buyer beware if you purchase Garmin's "low end" units. You will apparently not be able to receive a free update of maps, even if the unit you buy is already out of date.

Putting maps on sd memory card

For C330 owners that want to have both Canada and US 2008 map update on their GPS this is what you have to do.

Must have:
1 - Street pilot C330

2 - 512mb SD card
3 - SD card reader of some form (some cameras will suffice)
4 - Garmin 2008 Map Update North America

What to DO:

1 - connect the GPS to the computer
2 - Insert the Map update disk
3 - Install the Lower 48 states, United States
(Reason - the C330 has around 1000mb of memory and the "US 48 states" map uses around 900mb" while Canada uses 400mb...which is why you will need that 512mb SD card later)

4 - Once the GPS is updated with the US map. Browse the Map update disk contents. This can be done with going to "My Computer" right click on your CD/DVD drive and click on "Explore"

5 - Open the folder called "img"

6 - Copy the file called "gmappromU.img" file is around 430mb. (This is the map file for Canada)

7 - Insert your SD card into your card reader and connect it to your computer. A window should pop up. If not you should see it on your "My Computer"

8 - Once you have navigated your way into the SD card directory. Create a folder on the SD card named "garmin" (no caps)

9 - Go into your newly created "garmin" folder right click and paste the "gmappromU.img" file. (This may take upto 20 to 30 mins)

10 - Once the process is complete, Rename the "gmappromU.img" file to --> "gmapsupp.img" (watch for spelling, no caps at all)

11 - Remove the SD card, Turn off your GPS, Insert SD card into GPS.

12 - Turn on GPS, let it load, and there you have it, the FULL North America Map.

When you are searching a state or province (depending where you are located) it will give you an option which map to use, Canada/Alaska or the lower 48 US states. Select your map and you are set to Go.

Mapsource update CD

Hi check out this wed site, it will help. HT maps for the Nuvi are NOT for PC use. The map load onto the GPS as you install Mapsouce. Reinstall Mapsouce and take option 3 on the startup page of the program.

Good luck

Garmin Map update 2008

you will need to install the usb driver which should be located on the 2008 disk. When you attach the gps to your computer it should ask where the usb driver is located. If your dvd drive is (D) click browse and go the disk and find usb driver folder. I have purchased the new 2008 disk and had problems with it freezing on loader loading. I then browsed the disk and downloaded and then was able to get to the maps. I did not install it due to it asking what map I want to download. I wanted the whole thing so needless to say I am taking it back to walmart. I hope this helps.

Map data availability

"I tried to load the new 2008 City Navigator but the update was interrupted."

You deleted your previous maps, therefore there are no maps on the unit. Try reloading the maps again and this time let it continue all the way to the end. It will take a couple of hours depending on loading all maps or only certain states.
