Nav software update: Will it Affect Uprev?

Jordo! · 01-03-2014, 02:14 PM

Do I need to flash the ECU back to stock (i.e., remove uprev license) for a Navigation system software update or can I just leave it alone with uprev on there?

Again, this is an update just for the NAV and not for any other aspect of the ECU software.

Please let me know for certain ASAP!

Thanks!

You can keep the Uprev , navi has nothing to do with the ecu

That's what I had thought too -- but, you are 100% sure on this?

Ya... They could flash over the ECM , but if your going in for navi work they shouldn't be doing anything else

Okay -- whew. Thanks for clarifying!

Should I explicitly tell them anything to that effect?

As in "ONLY update the nav software -- so not do anything that alters the ECU", or will they just look at me like I have three heads?

On a related note, is the same true for body ECU stuff -- that alterations to that software are independent of the EFI ECU?

Cipher lets you access the bcm, so I think at least some of that is shared.

Does the Nav have a separate control unit?

I thought that it did (along with the body), but since it can probably all be accessed from the OBD port I wasn't sure what aspects of the programming code are shared and changed together vs. independently, hence my concerns.

Who's your tuner?

Keep it simple, just tell them only to update the navi

I'm pretty sure it does. I was under the impression the nav brain was in the back of the car with the amp for the Bose.

THat's what I thought too.

I'll make sure to tell them that only nav updates are to be made -- no touchy of the powertrain ECU.

Thanks, gents

The nav updates are through dvd's loaded into the head unit, right? They would have to go out of their way to even access the ecu.

Oh really -- I didn't know that! No CONSULT III involvement at all?

If that's the case, then I really don't have anything to worry about.

Is that for both software (e.g., music playing) as well as updating the location maps and such.

That's my understanding of the update process, but I could be wrong.

Update:

First, thanks gents -- you guys were 100% right regarding the navi updates not affecting anything.

Second, apparently the problem I've had -- the nav screen going blank occasionally as well as intermittent poor ipod connectivity -- is not merely fixed with a software update, but with replacement of the whole nav touch screen!

I'll post details when this is done as well as scan and post a pdf of the relevant TSB -- it's not 370Z specific, and I don't think it's been uploaded here previously.

Update part II:

Here is the TSB -- should I forward this to a Mod or AK?

If any mods are monitoring this thread, please feel free to move this pdf to the TSB repository.
