KLN89B GPS Question

[bentleg]

I'm having an issue with KLN89B GPS. Would appreciate advice from someone who is expert.

When flying a GPSRNAV approach and executing a missed approach, having pressed GOTO (missed approach holding point) and ENTER, when between the missed approach point and the missed approach holding point the GPS flips back to the runway reference point (final destination) rather than continuing to guide to the missed approach holding point.

Is this normal Am I doing something wrong?

I have one of these units in my private airplane, and have found that the 'logic' of the KLN89B is slightly obtuse, in some ways.
My suggestion, after the missed approach point, insert another fix...for example, this could be the alternate airport, or a fix toward that alternate.
I have found by doing so, it will allow the unit to sequence properly.

Hopefully

I posted the same question referring to a specific approach in an Australian PPrune forum, and got some enlightening responses.
