Arduino Mega ADK + Saintsmart LCD TFT comminucation pins

Other Hardware Displays

Hi guys,
I have an Arduino Mega ADK and a Sparkfun Shield CANBus that use the SPI pins to communicate. I would like to buy a LCD TFT display like:

but I am concerned. Which pins the display will use to communicate with Arduino Mega, because the SPI are used for the CANBus shield?

Do you have other suggestions?

Thank you very much in advance

Studying a little bit I found that, changing the SS pin, it is possible to share the SPI but, somethimens, the devices that share it do not release the bus also putting the SS in LOW status.

So...I am wondering how I can be sure that connecting the CAN bus shield and the LCD and changing the SS pins everything will be fine?

Someone can give to me advices

thanks
