mine would run, once i disconnected power it would not run again until a bunch of tries.

 

anyone on here have any leads on the small plastic gear on the end of the motors? i was so close to fixing this and now im stuck due to this piece being broken.

 

I am not sure but have you tried a hobby or RC modeling supply place? They usually have gear kits of all sizes for RC motors and servos. Not sure if you would find an exact replacement but might be worth a tray. Another option might be picking up a broken CD Rom or player and see if you can salvage one from that. Just some thoughts.

 

Ok I started to have the same problem and I don't if I should replace the motor or just pick up a cheap used updated navigation dvd, or just go with a whole double din after market system? Any help would be appreciated!

 

I was having the same problem with my original Gen 2/3 navigation system.

This post has a bunch of info and is very helpful. Tried a few things but the "No Disk Detected" continued.

Ended up taking the easy way out. Bought a used Gen 4 DVD unit. It is directly plug compatible with the Gen 2/3 harnesses. The only downside is you must also get a Gen 4 map DVD but being as my Gen 2/3 map was way out of date, a necessary expense.

The new system works great, is faster, and I have the V11.1 maps. All for about $400.

 

if I can get one of those motors I am willing to try it. Because I have already taken the unit out from the trunk opened it up and I couldn't find anything wrong with it. However, when I put the dvd in I can hear it trying to spin and the navigation on the console comes up but after a while it says no disc detected.

 

If you decide to upgrade to Gen 4, look for the part number 86841-50090. That is the part number I used to replace the Gen 2/3 ( part number 86841-33060 ) unit in my 2004 SC430.

I found the Gen 4 units were cheaper than the Gen 2/3 units, probably due to greater demand because of the higher failure rate. ( And why pay more for something that is not as reliable? )

You already know how much fun crawling into the "trunk" is and my eye-sight was not up to the challenge of replacing those tiny internal components inside the drive.

 

LOL I've gotten used to it! So I shouldn't have any issues installing that in a 2002? Thanks for the reply by the way.

 

Check and verify the current drive part number. If it matches, you should be good to to. It was a plug and play swap. Even the mounting screw holes matched up. The used Gen 4 unit I bought was from a 2005 Prius, but it's used in other Toyota vehicles as well, so go by the part number.

 

Ok I am going to have to pull everything apart again. Does the navigation software look different? Wouldn't it be better to get a new double din stereo system with navigation, blue-tooth and mp3 player that connects to the navigation screen up top?

 

The Gen 4 display is different. It does split screen, different colors, etc. Can't remember the Gen 2/3 display very well as it was always resetting plus we only had the car a month before the swap.

For the price and added features, replacing the stereo system is a viable option.

 

I am thinking instead of spending $500 on a used navigation system, I can spend around the same price and get one of the newer model double din systems where software upgrade won't be too much trouble as well. I don't know though, I have 3 options so far I guess. I can either get a motor and replace that myself, get a Gen 4 unit and replace it myself, or buy a double din blue-tooth, ipod, mp3 dvd-player and have someone install it for me. However, if I go the double din option I would want a video out to the original navigation lcd........

 

So for those people that upgraded a Gen 2/3 to a Gen 4, are you able to use Bluetooth for the phone now? Does the new unit function just like it would in a factory equipped Gen 4 car?

Thanks
