I've got an in dash monitor in my truck thats currently hooked up to a dvd player...I'm not realy in to that stuff anymore so i'm looking into selling that and getting a GPS brain unit that I can run topo maps on...Any one know how I can do this? Thanks

 

Anyone know how?

 

i know the Garmin has a Topo CD you can buy.... but i dont think it would work on an Indash one. i am going to get it for my Garmin Quest as soon as i get some $$$

 

Does someone make a hand held one that has rca outs so that I could hook that up? Or how do factory navs work with the indash screen? Thanks

 

factory nav systems usually have some kind of computer running in there.. they do a lot more than just nav (at least on the BMWs that i've seen)

 

The processing unit itself has programming that uses the nav map info. So you can't just put a map CD into the DVD - nothing will happen.

You *might* be able to use a handheld and jack it into an input to use the vid screen if your HU has such a jack, but I doubt it. I can use my handhelds with my laptop - but there is a program running on the laptop in conjunction with it. IF you could though, you'd still have to manpulate it with the handheld - not too convenient.
