Firmware 6.02-7155 - Fix for GPS Epoch limit on 6th April 2019

Recommended Posts

The attached firmware is the latest as of 22 April 2019 and fixes the GPS Epoch limitation in the BMW Nav computer.

 

This fix will allow the Intravee to set the correct date even though the BMW Nav computer does not correct for the current GPS Epoch (1024 week time periods).  The fix should work until 03:14:07 UTC on 19 January 2038 when the time_t variable used to hold the number of seconds elapsed since 1 Jan 1970 will wrap round causing all sorts of time based mayhem - year 2K will have nothing on this!

Brilliant, thanks Richard. Now I need to borrow a windows laptop so I can update mine!

If anyone really can’t update their Intravee due to lack of a Windows laptop, USB serial cable or general lack of computer skills, I will always offer an update service. Just send the Intravee to me with a pre paid self addressed envelope. For overseas users, you can PayPal me the cost of return postage. PM me if interested.

I noticed my Intravee II was no longer giving me the correct time/date and so learned about the Week Number Roll Over issue that happened recently.  With the sad news about Simon I had not looked into updating for many years... but thought I'd try a search just to see if there was a fix.  WOW!!!  I am so thankful and heartened to see his project still alive and extended with so many new (to me) "extras".  I dug up my old USB to Serial adapter, found the drivers online (took a while!) and had my Intravee renewed and better than ever in less than an hour!

 

RichardP, thank you very much for keeping up with this... you are truly amazing!!!

I just updated mine. I had very old firmware so the added features are awesome. Thank you!

But I noticed that if I’m looking at vehicle status after a few seconds it goes back to nav screen. Didn’t do that before. Is there a setting I need to adjust?

The most likely cause is not using the ‘rectangles’ button to switch to audio screen priority. It’s easy to forget to do this as it’s not very intuitive.

The button that looks like two overlapping rectangles, it's actually a head unit over a rectangle, it's position varies depending on your monitor type.  See the user guide Page 45 for it's location.  If you don't know what it is, it's the problem!

Thank you very much Richard to take care on this great project.

 

I'm running the Intravee with switch since a year or so and I'm very satisfied every single day entering my car.

 

Maybe I've overread this in the manuals and on the web so just a short question:

Will the settings remain during firmware update or do I have to configure the Intravee from scratch afterwards?

Worked like a charm, thanks :D

 

Just encountered that the ivee really needs to be in its working environment, meaning connected in the trunk. Just providing power supply on my desk leads to non-recognition due to the lack of ibus.

Yes, you need an iBus connection to wake up the Intravee.  After being disconnected for a while, connecting to 12V will usually wake it up for 1 minute which might be enough time to start uploading the firmware if you're quick.  When the upload starts the sleep timer is disabled so it won't shutdown on you half way through the update.

Hello all,my intravee is now randomly switching to the radio again and is doing it more often any ideas as to why,i have 7155 version loaded on to it just now.

Was this with the previous firmware of 7155?  If with the previous version, do you know which it was.

 

The switching to radio is almost always caused by the lack of a CD Changer response to a poll from the radio, often this is caused by the radio no sending the poll!!  It could be indicative of an intermittent iBus issue.  Another possibility is assigning the R/T button on the wheel to a function that switches back to the radio, the button message can be sent when the button is not pressed as this button works in a different way to all the others.

 

If you still have issues, best start another thread rather than muddle this one.

Hi Richard, was wondering what the symptoms might be on a MkIV nav setup running with Intravee without this latest firmware of yours...because I've not seen any issues on my setups (I have two identical ones). I have a Rover 75 and an MG ZT-T V8, both with a MkIV BMW drive and an Intravee running the previous firmware. As those cars didn't have a clock signal over the iBus originally, they also run a dedicated, battery-operated clock module over the iBus (someone from the 75 community created this many years ago). This allows to have ETA with GPS travel computes. All of that runs fine in both of my cars, they both display the correct date and time...and have been before AND after April 6th 2019. So what gives?

The only issue you’ll see is if you use the Intravee ability to set the clock from the GOS time signal. As the Nav does not interpret the epoch correctly (at all) it will get the time and date completely wrong.

 

if you don’t use the GPS clock setting feature then you won’t have a problem.

Thanks, makes sense. Will update eventually just for the sake of running the lastest build, even though I'be never used that feature...
