Hack the nav - enable trip computer and AC

[csimo]

Copy the Ridgeline .bin files to a CD-R and make sure the date is in the future. It should recognize it as a newer file and load it.

No such luck. It is still asking for the security code, but I have no way to input the data..hmmm.

Anyone have access to the tech manual for the nav system to see how to do a full system reload?

[csimo]

Hmmmm, if it's asking for the security code because the power was cut. The unit now probably thinks it's stolen. None of the input keys work at all?

Will send off a message about this and see what a friend thinks.

[quote=Drewbot]Ok... good news and REAL Bad news..
Now the bad..the RL has a totaly different interface than the ridgeline (twisty knob and no touch screen) and now my Navi is not responding to any keys..even the hard keys on the side of the nav.

Being an 05 RL owner I was afraid that would be a problem.
Others have been able to to enable the Honda/Acura trip computer
with methods in these threads: http://tl.acurazine.com/forums/forumdisplay.php?f=2
Mabe a differnt Honda/Acura Navi is more compatible.

I looked in the service manual and it did not mention any type of reset other than disconnecting the battery.

It did mention a "forced starting of display" option. Not sure that's going to help here and the text really doesn't say much. "Connect the SCS service connector to the navigation service check connector located behind the navigation unit."

The SCS service connector appears to be nothing more than a jumper connecting the two pins together on the navigation service check connector which appears to be just a loose two pin connector cable haning off the back of the unit.

Then it says " turn the ignition switch ON (II). Check that the system starts up and then changes to the Navi System Link screen."

I looked at every page in the Navi section and that's all I really see that might help.

I'll look at the unit and see if I can find the connector. Worst case I'll take it to the dealer and take my meds.

Funny thing is I think we are very close to a solution, somebody had to take the bullet so may as well be me. It cracks me up to see the Acura nav splash screen when I start the truck.

I was hoping we could find a way to reset the system without dealer intervention so that I could try the other 2 rom images to see if they work any better.

Hmm I wonder if the system is looking at the files for an internal version number rather than a file date and that is why the rom is not reloading. I'll dig around with a hex editor but I'd feel better if a real programmer looked at the files to see if they can spot the version info.

Alternatively if one of the folks from Canada who has a version "later" than 4.13c can email me the SJCA.bin and SJCA2.bin files off their DVD that might fix my problem too.

Thanks for the help folks.

Finally something I can help with ...its windows based so Just hit Ctrl / Alt / Delete

You need a way to edit the existing RL ROM instead of trying to use the ROM for another system. I've seen ROM editors for my DVD burner, but I doubt the RL is popular enough yet for someone to have created such a utility yet. Might be worth looking for though.

Hows this?

[csimo]

The SHJA bios files are for the Odyssey. Problem is that Honda (in their infinite wisdom) has disabled the trip computer on the 2005 Odyseey navigation system too. The Touring model has a simple trip computer outside of the nav system.

Here's more for those that want to play around. How about a digital speedometer?

Be warned... mess with settings in these screens at your own risk!!!

"MENU" + "MAP/GUIDE" + "Cancel" for 5 secs enters standard diagnostics mode.

Then "GPS Information" button:

Then "MENU" for 5 secs and you get the "GPS Detail" screen.

You can also hit the "Delete" button and get other info.
