I bypassed the parking brake when I first bought my N1 and everything worked great while driving. Then I upgraded to level 60. I realize that I can no longer perform the same functions while driving with this level. But I am curious as to why I get the connection error message even when not moving.

As far as the unit is concerned my parking brake is on and I am stopped. So how can it determine that there is a connection error in the parking brake? It does not affect operation after I reply OK but it is a nuisance and I am curious.

I may eventually do the soldering bypass.

Well my first searching did not answer my question but since I have done this post I have spent more time browsing and have found that the N1 gives this error message unless the it sees the parking brake on AFTER booting.

I don't understand this logic. Don't most people have the parking brake on when they start the car and the unit then comes on?

In any case if it is true that you can get all the nav functions by installing a switch to ground the parking brake signal after booting then that seems the easiest way to go.

I can do the solder for you if you're interested. 75 dollars including return shipping. Check my ebay profile: turbo_tunes

OK, so I put a switch on the parking brake wire to ground it but it does not seem to make any difference. Sometimes when I turn the unit on I still get the parking brake error message even with the switch off. Even if I don't get the message after I turn the switch on all the functions are available and then after a few seconds I get the message and the functions go off. Is there some sort of sequence as to when I should turn the switch on? If not I wasted a lot of time.

for me simply pressing the little pen hole reset button on the front got rid of the parking brake error message. My parking brake connection is also grounded.
