Question about Garmin StreetPilot C330 GPS Receiver

PC can't communicate with GPS unit for initial map load

Repeated tries to load maps on new unit get problem message re communicating with PC (Compaq Presario). Garmin help desk sent email telling me to be sure I'm plugged into a USB on rear of PC (I am), then sent email telling me to check my chip set. When I look at USB controllers in device manager it just lists "standard enhanced PCI to USB host contoller" and "standard open HCD USB host controller", no brand name of chip set. Garmin's email said I may need to buy a new chip set (I don't even know what that is), e.g. Syba NEC & install in my PC. Any suggestions will be appreciated. Thank you!

Re: PC can't communicate with GPS unit for initial map...

It will NOT show up under USB controllers. It should appear as "GARMIN Devices" in your device manager. Mine is right under Floppy disk drives. Do other USB devices 'bong' up when connected and 'bong' down when taken off? Of course you have to have your audio on for that. The GPS should 'sound' just like any other USB device when attached or taken off. I find that GARMIN help is of no use. Forums like this have helped me far more.

How do I program my garmin

Your Garmin should have maps factory installed that load when you turn it on. If you want to update the maps you can 1) take the unit to a Garmin dealer to get updated maps or 2) Connect your unit to PC or laptop with internet through a usb cable and go online to You must install a small program in the computer- Garmin Communicator - so your unit can communicate with the website. Go to Map Updates and download the update into your gps. You can update one time each year. Hope this helps.

This is an indication that the map or map unlock key is either missing or corrupted. If you have registered your unit with Garmin, try connecting to your PC and try downloading the map again. More info on missing maps can be found here:

I purchased the new maps for my Garmin Nuvi 660. Before trying to install the disk, I first tried to update my firmware. After opening the download, the install program could not find my unit. The same...

Most likely the firmware is corrupted and not allowing your unit to get to the communication routines that allow it to talk to your PC.

Please see this link: Your map & firmware issue can be resolved there.

2009 map update not loading

Fixed. Called Garmin. It seems that version 4.90 FW on the Nuvi 350 (which came shipped on my 350) has a bug where it cannot communicate with the Garmin software either to update maps or update FW. Tech from Garmin e-mailed me a patch that I copied into the Garmin folder on the Nuvi itself, via USB and Windows Explorer. I then rebooted it; the patch installed itself which then allowed the unit to communicate with the map upgrade software and all is well. 2009 map update is now installed and the Nuvi is working fine again. Haven't tried upgrading to newer FW yet; will probably leave well enough alone.

2009 map update not loading

Does it recognise the Nuvi? Are you connecting it through a usb Hub. Are the drivers for the nuvi installed properly? Usually there is a folder named USB, thats where the correct drivers reside, and that's where you tell the computer to look when it asks for the drivers.

Garmin Streetpilot i3 GPS cannot load map to memory card

A way around this is to insert the SD Card into the computer (SD Card reader), point the directory to the card and install the maps like that. I had to do that the first time I bought my unit because I couldn't figure it out and got frustrated. So I thought of this easy work-around.

Cannot load map in my Garmin Streetpilot i3 GPS

i dont think you can upload maps to an i3, it can only load pre-loaded maps on micro-sd cards.
