How did you wire the nav to the horn?
Yo must connect the + wire of the nav to the brown cable of the horn an the negative wire to permanet ground (yellow arrow in post #3). Not to the second wire of the horn.

On my Honda NTV +12V is via the horn button. There is good chance that the Pan is similar and the wiring to the horn will not work.
Thank you for this helpful information :rolleyes
