BTW, I never actually turn off my Kindle when we take off and land. I put it in the pouch on the seat back in front of me, but it is still on. Some people might put their Kindle into sleep mode, but I doubt anyone actually turns the thing off.

What about this?

In March 2004, acting on a number of reports from general aviation pilots that Samsung SPH-N300 cellphones had caused their GPS receivers to lose satellite lock, NASA issued a technical memorandum that described emissions from this popular phone. It reported that there were emissions in the GPS band capable of causing interference.
