I recently put in a pcm with ext dvd nav system all works well except the fact that the arrow doesnt always follow the map, it goes off on its own and doesnt follow the map when the car turns. i have the latest updates on the pcm and nav software. where is the problem?

Antenna? Check for received satellites quantity when it happens.

Take a look in the menu, till you find the setting NAVI FIX, cancel this. There is a chance that the module jumps to navi fix.

Controls the map and compass. If the setting is OK ( navi fix is canceled ) go back to FACTORY SETTINGS and do a test drive, if the problem still occurs go to the dealer to check with the PIWIS tester. You have to know that the arrow disappears if you are on the highway for more than 20 Km ( same road ) turns or straight ahead, this a normal phenomenon.

i just went to the pcm manual (see the manual section of this forum) and the nav fix works the volume of the nav syst with respect to the radio/stereo volume. i doesnt say anything about compass readings or navigation settings...

ok so after lots of research i found out something very important, there are 2 types (at least) of dvd navs, one that mounts horrizontaly and one that mounts vertically, if you mount either one the wrong way you will get very erratic nav operation, i unfortunatly got a horrizontal one and mounted it vertically in my gt3, i took it out and placed it flat (horrizonatall) and it works like a dream...now i know and you all know,,,,,,
