  • StreetPilot c320

    Hi All,

    Sorry if this is an obvious one but... I have an older StreetPilot C320 and want to install a new(er) map. I currently have City navigator North America NY V8. I have the keygen util and downloaded the CNN.America NT2011.10 3D but after I copied the .img and .unl files to the SD card, i get a message on the StreetPilot telling me to use the software utility to install new maps. Perhaps Im overlooking the obvious here but, how do I install the new maps (and do i even have the correct version)?

    Thanks!

    Did you place the files in a folder named garmin ?.........was the IMG already unlocked?....if so you don't need the unlock file

      I copied the files to a folder I created named "garmin". No it wasn't already unlocked. I used the unlocker tool, and created the .unl file and placed in also into the x:\garmin folder. That didn't work either. Both times i received messages on the Street Pilot to use the software utility to install the maps.

      I then tried to use mapinstall. It found both my original (when purchased) garmin map (unlocked) and the newer map (NT2011.10) which it said was locked. No matter what I've tried I can't seem to get it unlocked. I'm stumped but I'm convinced that I must be missing something very basic here.

        Did you use the new patched mapsource/mapinstall?

          Yes I have and no difference. it seems that no matter what I've done the NT2011.10 map always is reported as locked. My only listed option is unlock it via the garmin website. I've tried unlocking an image file and just placing in on the SD card and that hasn't worked yet either (tells me to install the maps via the software). So I'm stuck. Not sure what to do/try next.

                HowTo Use bigger SD card

                My current 2gb SD card is too small to fit the latest European gmapprom.img file (2.06gb)

                I purchase a couple of 4gb SD cards and tried the following:

                Copy files off the 2gb SD (European) card to my PC
                Remove 2gb SD card to safe storeage
                Insert new 4gb SD card
                Format SD card
                Copy files of 2gb SD card from PC folder to 4gb SD card
                Test on Street Pilot 320
                See message "Loading maps..."
                Eventually see a message "Please use the provided PC software to load maps"

                PC is Win7 Pro system

                  A few things to look at...

                  If you downloaded a gmapprom.img file you must rename it to be gmapsupp.img for use on an SD Card.

                  Make sure you have updated the 320 to the latest firmware (check with the garmin webupdater). Some of the older gps models required a firmware update to support SD cards larger than 2 gig. I don't know about the max SD card size in a 320.

                  The SD card shoud be formatted as Fat32

                  Maps should be in the garmin folder of the SD card and named gmapsupp.img

                  In the event that your 320 really doesn't support an SD gig card larger than 2gig OR the possibly the 320 can't handle a map file larger than 2gig you can always download a mapsource version of those European maps and create your own custom (smaller) IMG by choosing only the maps you want/need. That file will be much smaller and will also fit your your 2gig card.

                    Thanks for the assistance. I experimented and confirm that the Street Pilot 320 cannot handle a SD card bigger than 2gb. (Yes, I updated the firmware)

                    That's Ok with me. The restriction is that I can't fit ALL of Europe onto 2gb.

                      This is my first Navi ever, but I'm no stranger to it, I just never owned one till now. For the features I was looking for, I narrowed my options to The Garmin 2620, Garmin C330, and Megellan 700. Needless to say the C330 was my pick.

                        Re: HowTo Use bigger SD card

                        I have a C320 that had a 256mb SD card.

                        Recently I purchased a battery for it and it as good as new again.
                        While I was at it I got a 4 GB SD card as much of the maps are large now.

                        Even thought putting in Ireland only takes 50mb it was telling me that there was no room for POI (hope that its not internal memory) because I think those units have only 32mb. Anyway thought 4GB would be well enough future proof etc...

                        After spending many hours first not been able to read the new card with PC slot trouble then formatting now the C320 keeps showing "loading maps"

                        I found a post on a forum somewhere that led me to Garmin site where it was claimed that 2GB is the max
                        https://support.garmin.com/support/s...-000000000000}

                        However the store I purchased it from in Amazon has this ....4GB SD Memory Card FOR Garmin Street Pilot C310 C320: Amazon.co.uk: Electronics

                        Is this misleading information....Is there any firmware that can be done on the unit itself ?
                        Unlikely as I updated it as far as it goes.

                          I have a C320 with a 4Gb SD card working perfect. It´s a SD card not SDHC card.
