(see attached image for explanation)

I followed a tutorial already to remove this nav system out of my 2004 es330 and reinstalled to see if there was a wire loose or something-obviously didn't work.
Everything works (cd/radio etc) except the display. I can't access anything such as inputting an address to use the navigation.

Anything that shows on the display blinks and flashes-it also changes patterns or the direction it flashes when I go over speed/road bumps.

Should I replace the display? (If I do, are any aftermarket ones compatible plug and play?)

Thanks much!

 

Any suggestions on an aftermarket in dash GPS to replace this one? Are there any that won't require a rewire or harness?

 

Take a look here

...wait you already have the nav never mind you don't need the bezel. How much are you looking to spend? There are so many aftermarket units out there.

 

I don't really want to spend more than I need to... I think I be getting the Pioneer AVH-X2500BT?

 

Not exactly the same case, but I loved this dude's write up:

I'm going to do the same thing myself with a pricier Alpine unit:

I'm going to keep the car for awhile so spending the $850 on ebay I think is worth it. In your case, just get the harness and mounting brackets and get the unit you mentioned. I think that's what you'll need bare minimum. Good luck!
