Truvelo not detected on Garmin C310

[nibbo68]

I'm new to all this, just bought a Garmin C310, downloaded speedcamera database and all seemed to be ok. It warned me of approaching cameras by bonging and flashing a red strip across the top of the screen and if I exceeded the speed limit it showed me the position and type of camera I was approaching and bonged more frequently. But today, I passed a Truvelo camera and absolutely nothing, no bonging, no verbal or visual warning, just didn't do anything. I checked to see if the camera's on the database and it is. I checked it in 'My Locations' and 'Custom POI's' It's Truvelo 5449. Any ideas why this didn't alert me to this camera. I know it's still working with others as it warned me about a Gatso 5 mins later.

Thanks for any help.
