I have to apologize for any errors in the Owners Manual for the MX-900. It will not support multiple backlight colors, it has only blue backlighting. I will double check the weights, I can't answer which manual has the error. The MX-900 is considerably lighter than the MX-950.

As to the speculation on the Navigate- (Back to the last device you jumped from), we are working on it for all three remotes (MX-950, MX-900 and the TX-1000). It should be available in a few weeks via live update.

Best Regards,
