I appreciate all the feedback. I failed to mention I don't have audio but the problem is the amplifier which the dealer is replacing next week. I do have a NAV display but just the basic menu, no maps. So maybe only the DVD player in the trunk was fried? Besides the amp ofcourse.

 

Do you get a 'no disc' message or similar?

 

Johan was it a 2006-2009 prius unit?

 

No I don't get a 'no disc' message. The information screen comes on and also the display screen. On the display screen you can adjust brightness and contrast and that's it.

 

Yes, it was. In post #12 you'll find the part to look for

 

Johan, is the map image sharper than the Lexus unit? My wife 2007 Prius Navigation image much sharper. I wonder if it's sofware related or it's the unit.

 

From memory the image sharpness doesn't change.
It's pretty outdated compared to more modern systems, but it gets me where I need to be.

 

Could still be the DVD / Navigation unit in your trunk, but I'm not sure now.
The navigation in my SC430 wasn't working when I got it and I just replaced the DVD unit because I had a spare, but I can't remember if it just didn't work or if there was a message.

 

OK thanks. I'll hopefully know more in a couple of days.

 

Dont spend your money on it, there is no point! Upgrade to gen 4 will cost you a lot and still wont give you latest maps and fixing gen 3 is pointless in my view. Maps are so old and no life traffic information. Phone is much better!

You can get a Navtool to use your screen as phone mirrowing and add a backup camera. That would be a much better use of your money.

I am also doing a similar project with complete screen replacement right now but haven't quiet worked it all out yet so wont recommend it until I finish.

 

Alex is right, don't waste you money. I don't use the Nav system and/or screen for anything besides back up cam.

 

I'm not planning on putting big bucks in the nav system. Just want the radio and CD player to work. Backup camera would be nice so I'll stay tuned!

 

 

Bob,
The latest navigation apps in your phone ie : Google Maps , does not use cell phone coverage alone. So you can actually used it if there is no cell phone coverage by utilizing the GPS sensors in the respective phones.
The trick is, you need to download the portions of the maps in to the phone itself . Such as when you arrived in a new area, at the airport / Starbucks , I usually used the local wifi / cell phone data coverage to download the Google maps in the vicinity .. Then when I am travelling / driving , I am not encumbered with getting the new maps update ,, but just use the GPS sensor to track the local maps data that was previously downloaded
