Question for the Toyota and Technically minded experts. My L/Cruiser has a build-in GPS system. The system operates from a CDRom disk, distributed by "Whereis" V12.
Question is, would it be possible to get a line from this system, picking up the NMEA signal, and connect direct to my laptop in the car and Oziexplorer via the serial port
If it is possible, how do I go about it.
Cheers

The sat nav in your toyota runs a gps wire to the gps aerial which is on to of the instrument cluster, a reverse wire and a power wire,
it runs a multi plex cable from the dvd player/processor under the pass
seat to the head unit. so the answer would be very hard to give unless you wanted to bare the cable and find the correct wire which no one could tell you it would be trial and error......

Given that it doesn't need to give out an NMEA output it probably doesn't anyway. The aerial wire is only the signal to the "smarts" so it won't be that. The processor probably only outputs the display data to the screen. If the nmea is available anywhere at all, it will most likely be off the board somewhere and without a PCB diagram and a penchant for damaging a very expensive part you probably won't find it.
Get a bluetooth GPS (wireless) for a couple of hundred bucks - possibly 20% of the value of the damage that could be done if you smoke the factory unit. Definately the cheaper way to go. Some like the Haicom unit I use are even rechargeable (about 20hrs life) so when you are using it there's no leads anyway. And no risk.
