After the rollover to week #860, the thunderbolt will not make position for 2

The module will work fine after this 2 hours."
Have the Motorola Oncore/Navman/Jupiter receivers also been checked for this

Strange that at least 3 independant firmware trees/development teams should
chose the same magic wk860.
Actually not that weird.
They might all have inherited a published code snippet. There's a

everybody uses, and it derives from some article published in the 70s or
early 80s for an 8 bit micro.
