2011 BMW NAV disc = Expensive!

I recently purchased Google's Nexus S with Android smartphone for $99 dollars with T-Mobile and it includes navigation (for free) with free updates included. That navigation system is faster, better, more efficient, and speaks the road names. It's even better than my Nuvi Garmin 780 (if anyone is interested I'm selling it for $150).

The other day I even used it while riding my motorcycle without even looking at the screen. I simply plugged in the headphones into the smartphone, put the earbuds in my ears, threw my helment on top, and was navigating by just listening to the audio. Amazing technology.

True, but i love how my navigation screen has computer information and radio stations on a big display. Tells me average gas consumption etc etc.

It's not as good as the Nav options that come with some of the cooler phones out there, but it will get you where you're going and for 50 bucks is pretty nice.

My car is still under warranty till next September, will upgrading to the bmwnav.net firmware void my warranty?

No. It's the same as what you'd get with the 200 dollar disk or just the firmware update from BMW (about 8 bucks for firmware. (I have both, BMW and a disk from the link I posted earlier and both are the same).

how would u downgrade your version so that you could reupdate it again with another new splash screen or icon updates?

:

Downgrade? Splash screen is available through bmwnav.net or by more or less hacking the nav disk (search).

in the research i've done, it mentions that the system will not update if you are updating the same version to it's self. Which means...

I update from an old version to a new one and "hack" the update to put a new splash on..

when I hack another update (which is now the same version since I updated already) and I try to put a NEWER splash screen on, the update wont take effect... so I would need to "downgrade" to re upgrade is what it sounds like.

Not unless you roll into the dealer complaining your NAV doesn't work for whatever reason. Just pop in the original disc before any dealer visits if you're paranoid.

Ah...yes, that could be, and I think I saw that at one point too now that your remind me. Z4forum is a good source on this as that's where the experts on this type of hack are.

Can you show how you got to this? I tried to get to the unit to get my BT code a week ago and got completely lost.

Any idea?

The unit is mounted in the trunk on the drivers side. I got my BT code by popping off the driver side subwoofer and looking back into the trunk where the label side of the module is facing forward. A number of posts show pictures.

The posts usually show pictures of the TCU unit only, and not the steps required to get to them.

How did you pop off the subwoofer?

Sorry - Subwoofer cover. Plastic spatula!!! Shine a flashlight beteen the subwoofer frame and the edge of the enclosure. It helps to also pop off the vent looking piece on the side. The back of the TCU where the code is printed (PK in Ron's photo)

would be facing you.

I used a wooden dowel to manuever the cable bundle away from the label to show the code.

Other options are to remove the carpeting in the trunk and pull out the TCU module - pain in the rear - or have a dealer readout the code (for which they may or may not charge you).

There is a file on the disc that stores the firmware file version. Changing that to any number other than the one you currently have installed will cause the update to kickoff. You can find more info about this at X outpost forums. It's not as straightforward as it sounds.

Thanks! I'll try it tonight.
