I've received mine and can't get it to work in my car stereo even though it's supposed to support SDHC cards.

Oh well back to the drawing board!
Suggest testing card with a reader on your PC.

This is a very cheap deal but I have had a lot of compatibility issues with Kingston/Transcend SDHC cards. They don't get detected on some computers / need formatting again / they don't work out of the box!
Personally, from my own experience, I havn't had any grief with sandisk SD cards. They have worked straight from teh box - no issues. Maybe it will help somebody!
I ordered 2 Transcend & 1 Kingston card - all fine for me, 2 for cameras one for TomTom. All work fine. I am using a SanDisk card reader to test them though. Could be a dodgy card reader rather than the card?

SanDisk cards are good, but the class 6 ones are way more expensive than these!!!
