Microsd card won't read

The LG900g works with microSD cards. Your 8GB card is actually a microSDHC card. While microSDHC cards will fit into the slot, they are electronically compatble and will not work in devices not specifically designed to work with the higher-capacity cards. You need to use microSD cards, 2GB and smaller.

The MP66 can read microSD cards. Your 8GB card is actually a microSDHC card and will not work with the MP66. You need to use SD and microSD cards, 2GB and smaller.

I found the solution on my own. My PC is a Win 7 64bit machine and I was using Google Chrome Version 18. When I tried the download again using IE, it worked fine. I now have 3 full maps on my Nuvi 1390 (i in the internal memory and 2 in the SD card) and can access each one without a problem.

Your 4G card is probably an SDHC card which won't work in your camera. It only takes SD cards.

Sir,
Yourcell phone supports only MicroSD in it so you can purchase the card by the this name "MicroSD" Your card may not be recognized if its corrupted or have any other format then"FAT" please observe "FAT" not "FAT32".

Your printer may have issues reading SDHC memory cards. The Secure Digital 2.0 standard (SDHC) is not backwards compatible and requires SDHC compatible devices in order to function.

First, make sure it's a microSD card and not a microSDHC card. If it's larger than 2GB then it's a microSDHC card and won't work. Second, make sure all your music is in a folder named "MUSIC".
