Any body tried BT adapter which work with Torque App ?
I ordered 3 different adapters but non of them worked with my 2004 C5 ?

There are a LOT of half-baked knock-offs of the ELM adapters out there. The market is so flooded with crap that it's hard to find good ones.

There's a compatibility list here, it's probably best to stick to devices that are on their list:

I think its not a knock off adaptor problem because when I tried them with my 2009 Acadia or 2008 Avanache they will work with out any problems
But with my C5 it will not connect for some reason

So I need some body to send me a link for approved adapter for Corvette C5

2008 and later cars use the CAN version of OBD2, whereas the C5 era cars use the VPW version. Clones tend to have issues with VPW support.

FWIW, I can confirm that the ObdLink ScanTool SX supports VPW, but it's USB. They do make a Bluetooth version though, and it's in that list I linked to.
