How to: Update your OEM Nav to the newest maps.

Okay, first off, I'm not going to explain how to get yourself an ISO of the latest maps. If you don't know how, sorry.

 

Now that we've gotten that out of the way for the 1%, I've tested and found that yes, you CAN use Toyota/Lexus Gen4 GPS data discs in the OEM Subaru Nav system.

 

I believe the most recent is the v13.1, which were released in October 2013. BitTorrent is your friend in getting these. A search on an appropriate website of "Toyota-Lexus Gen4 v13.1 Navigation DVD - NA - U28" should get you to the correct one. You want to make sure that it's for a Gen4 system and that the description says it's for a bunch of Toyota and Lexus vehicles in the 2004-2007 model years.

 

Once you have the ISO file, you'll need to burn it to a disc. You'll need a DVD+R DL disc. I wasn't able to get a disc that the nav system liked using Astroburn Lite, however, with ImgBurn, I was able to use the option in the bottom right of the main window to 'Change Book Type', then in the LG tab, select DVD-ROM and burn away.

 

Simply boot up the nav in the car and once it's running, swap out for the newly burned disc. On a side note, it appears that more data fits in a smaller space now, as there's only 1 disc needed for all of North America instead of the two discs needed originally.

 

No more being unable to set a course for a new location!

A couple of other notes on this:

 

1) You can also find these DVD's on EBay pretty easily. They're also selling for less than $50 if you'd rather not deal with getting an ISO image and creating your own DVD-ROM.

 

2) I had to run the Tire Calibration function for the maps to read correctly.

thanks for the heads up will try this next week.

Quick note for anyone who uses these maps - if you disconnect the negative battery terminal, you'll need to insert your original Subaru disc on boot up. Once the nav has booted, you can then change back to your new map disc.

Totally worked for me without disconnecting battery - Just had to use the OEM Disc to boot the map and then swapped it out for the 13.1 map.

 

Thanks!

Gonna have to give this a shot. Mine are a couple updates old.

Hmm. I recently updated mine using another source, I'll have to see if this has newer data. Although my nav is mostly there for show nowadays, I use Waze for my nav needs.

With or without voice nav?

With or without voice nav?

 

If you're asking about my update, mine has nav, it's an official Subaru image. The Toyota one apparently has no audio (from what I have read)

That's correct. I checked the DVD's and there's a couple of files I presume have to do with the voice nav present on the Subaru disc that's not there for the Toyota disc. That's the reason why the Subaru version takes two discs - those voice files push it over the 8gb limit.

 

Now, if we could figure out how to swap out the DVD drive for a BluRay and have it still read properly, we could put the voice onto the Toyota disc and have both.

 

However, I never used the voice features in any case, so their loss wasn't a big deal to me...

zombie.. but ..

 

DVD+R DL discs employ two recordable dye layers, each capable of storing nearly the 4.7 GB capacity of a single-layer disc, almost doubling the total disc capacity to 8.5 GB.

assuming you have the hardware that will read it... the oem nav unit is NOT a spring chicken
