Hint: All the US non NAV 100 series I have seen come from Hawaii
I agree with others failures are rare

While dated and not visually appealing, the OE nav head works fine and the Mark Levinson isn't bad even with paper drivers. Bluetooth input and ram windshield mount and you've got current nav and wide ranging audio selections. Not worth a Frankenstein truck to fix. Rob made a valiant effort a few years back. If there was a feasible work-around he would have found it. Enjoy it for what it is.
Re OE swaps: nav was a factory option not a dealer option. Seems like there was discussion a while back that it was more involved than just a pnp front end swap (computers and harnesses too?)
I like your optimism and while that would be fantastic, this is a very small market vehicle and the replacement electronics must interface with closed source and largely undocumented OE body control computer. Not to mention the unique form factor and buttons. It's a tall order to expect the market to find a replacement for our trucks.A few years ago is a long time when speaking electronics and technology. I agree Rob made a respectable effort looking at those posts. However, with the increased amounts of used vehicles showing up with nav/climate integration and people wanting to change it out, there is a growing market for conversions. There WILL be a solution to this as available texhnology advances and demand grows.
How much of this can be cured by going to poly drivers and replacing the OE amp?NAV would not be so bad if Toyota used the same Mark Levinson system Lexus used.
Worst case scenario you could disassemble and paint the trim. Virtually no chance of matching the buttons, but a slightly contrasting color would work.
It's rare enough to find a 100 in a yard, let alone a non-nav unicorn. There's only a handful of non-nav 03+ 100s in the US to begin with.
And I have one. Want to install an aftermarket nav unit though.It's rare enough to find a 100 in a yard, let alone a non-nav unicorn. There's only a handful of non-nav 03+ 100s in the US to begin with.
Interesting...I have just started looking into this myself. It's the only thing stopping me from upgrading from my 99.
Has anyone looked at naviav.com? I just started chatting with them.
They make a unit that replaces just the screen and keeps the heater controls. Has a hideaway unit of some sort cd, nav, DVD, Bluetooth.
China manufacturer of unknown quality but not many other options. I'd prefer a kenwood unit but this may be worth a try.
