The latest version of Garmin Express provides the ability to install a map update directly to an SD card.
The SD card installation option will only appear when updating a compatible device that does not have sufficient internal memory for the largest allowable map region. When using the SD card installation option, critical files are loaded to the SD card so it must remain in the device after the update to ensure full functionality. For the largest size SD card a device can use, refer to: What is the largest size Secure Digital (SD) card that an automotive device can accept?
The SD card support during the map update will only function with up-to-date software. It may be necessary to update the device's software with Garmin Express prior to updating the maps. These devices do not support the SD card option:
nuvi 300 series
nuvi 500 series
nuvi 600 series
nuvi 800 series
nuvi 805 series
For devices that do not support using the SD card with the map update application, any maps that do not fit in the internal memory can be installed to the SD card manually, using these instructions:
You can download the US basemap for the 500 at http://www.megaupload.com/it/?d=EJTNQH03 Rename it BASEMAP.MGI Then copy it in the directory "background maps" in the SD card of your 500, by using a SD card reader/writer. Insert
the SD card in your 500 and connect it to your PC; then turn it on;it
will turn on regularly, because the basemap in the card will be
detected; turn it to USB file transfer mode, and copy the basemap from
the SD card to the directory "background maps" of the 500. If you already have the file ..just rename it like I said ..and copy it ..using the sd card in the reader...Than if it is not functional ..just reset it ..and reload the file the proper way by reloading maps..
Some SD and MMC have a security feature in them. If so you will need the disk that came along with it. After you install it then that's the time you can fully utilize your SD/MMC. SD means Secure Data / MMC means Multi Media Card.
If your card reader is not appearing in the My Computer then check if it is detected in the Windows device manager. Go to START > CONTROL PANEL > DEVICE MANAGER. Usually it is under the category of Disk Adapters or Human Interface Device. If it's not present then unplug and plug the device back in. Or try a different USB port to see if that will work. If it doesn't then most likely the reader is defective. But if it is detected and still not able to read the SD/MMC and the SD is being read by a different computer then the issue could be that the SD is not compatible with the reader.
Try cleaning the pins of SC Card with contact cleaner or alcohol if you prefer make sure its dry enough before inserting. If nothing happens try detecting it on PC Desktop with proper Card reader, backup files if you still can then reformat thE SD Card. Reinsert in your HTC G1 if successful reformat it again using your HTC G1 to acquire compatabilty on the device.. hope this help...
If you have TomTom that have the slot for SD card, then it should accepted the SD card. The instruction for how to use the SD card is simple, but it is hidden in the TomTom Home, that's why it's difficult to find it. Below are the instruction how to use the SD card.
1. Format the SD card (FAT32) and do not stick the SD in the slot yet
2. Run Backup (connect TomTom device to computer)
3. Disconnect TomTom from computer and turn off
4. Slide the SD into the slot and connect TomTom back to computer (choose "yes")
5. In the TomTom Home menu, Choosen Backup & Restore >>> and choosen Restore
TomTom Home will add all applications to the SD card. So the internal memory still have the applications and the SD card also had the same applications. Everytime you slide the card in, TomTom will automatic detect and use it as its primary storage, if it not detect, you can go to the device menu and pick the device to connect to.
Whenver you take the SD card out, then TomTom will use its internal memory.
Perform the following procedures when your digital camera does not detect the SD card.
1. Restart the camera
Turn the main power OFF, or open the battery cover or SD card/battery cover to remove the battery. Make sure the SD card is fully installed. Then, turn the main power ON, or insert a battery again and close the battery cover or SD card/battery cover until it latches.
2. Initialize the SD card
Format the SD card with your camera.
Formatting procedures varies depending on the camera model. See the Camera User Guide supplied with your camera for the instruction to format the SD card.
When formatting the SD card, slide its tab upward to cancel write protection.
It is impossible to format the SD card while it is write protected.
3. Check if your camera detects other SD cards (If you own multiple SD cards.)
If your camera does not detect the SD card after performing the procedures 1 and 2, check if the camera detects other SD cards.
If it does detect other SD cards, the SD card that wasn't detected may contain some problem.
