i bought a 02 a4 with a eclipse navi. now it works fine except for the turn by turn function on the navi. i get a check speed pulse....which is what i believe is the prob...but a couple of days ago when i was gonna head to a gtg and i punched in the address where i was going it was giving me turn by turn instructions...which i thought was odd...so it was working...now i have the same problem with the speed pulse...kinda pissed it only worked that one time since i bought the car. ive had this car for what....2 months now...anyone with a similar navi that can help me out with this problem....any idea where the speed pulse might be...like where is it tapped to...cuz the person who had the car previously had it installed where it thinks the parking brake is on so that it can play videos while the car is moving. any help would be appreciated. thanks. oh my model eclipse navi is the 5435...one model down from the 5500 or 5510 i believe.

 

anyone?
