I recently purchased the Cubbycam from Ed Woz for my 2008 Chevrolet Silverado LTZ which included the compass and outside temperature indicators in the mirror.
The kit was very complete and professional quality. Installation was straight forward following Cubbycam's detailed instructions
and the final results appears like a GM factory installation. The system works really well in all light conditions.
I highly recommend this product.
