How to update MAP data on 2011 RX450h
Let say I can get my hands on one of those USB keys that have the latest MPA data for my 2011 RX450h. Is there any tutorial on how to actually update the maps, or does this HAVE to be done at the dealer?
Thanks in advance for your help!

It is very simple. Find a closest dealer. They will be able to get new maps installed based on the USB key you bought. Expect to spend about $150 in labor.
Lexus Nav units are not self-updatable. Their tech hasn't caught up with the 21st century yet.
It took 2 trips, one of which was overnight, to get the maps updated in mine. Got a loaner both times. But that was a complimentary update that I got out of Lexus because the maps were really out of date on a brand new vehicle. Not that they got that current after the update.

Nope, not since Lexus went to USB. You can buy the update for less than $100 from CL sponsor, Sewell. Then add the labor cost. I can't see it taking more than 1/2 hour but they probably charge an hour. I plan on doing this next month when I get the 450h serviced.

I recall that someone on the forums was able to do it themselves, but it was difficult and not worth the effort. Even dealerships have problems updating the software.
If you want to learn more, recommend you look up threads with the word 'techstream'. This is the software that Lexus uses for multiple configuration options, but unfortunately there doesn't seem to be much of an interest on it on the forums.
Good luck,
Eric

When I got my free update, I watched the tech. He gets the key (a USB flash drive) from parts and plugs it into his shop computer (that's plugged into your car). The shop computer connects to a server somewhere in the ether and verifies the key then downloads the upgrade to your car's 'puter. The parts dept issued the code (different each time). It's pretty much fool proof now re: cheating and using a disk which can be duped. Gotta pay to play . This started with the Gen III models.

The problem is, the usb drive doesn't contain the actual map data. It's just a software key. The actual map data has to be downloaded via the Techstream laptop.

I think they have us on this one. No homemade work around.

I just had our 2010 RX-350 updated. It was two versions old from the previous owner. Pretty much described to me the same way. It takes a USB key and the Service Tool / Laptop to down load the software. The dealer gave me a loaner to run my errands and couple hours later they were done. Cost $99 for the software and $125 for an hour labor.

Firmware Update Changelog?
I have a 2010 RX350 that hasn't had a software update for 2 or 3 years. My iPhone 6 doesn't work as well as it should using the direct USB connection. Often you can play a podcast or song, but pausing or changing songs/pcast often results in a hung up audio screen.
I am aware bluetooth can be used instead. However, audio through the USB is higher quality than through bluetooth.
In addition to fixing this issue in firmware (I hope), wondering if there is a change log showing dates/changes in firmware. I assume the dealer will charge me to update the firmware and I am trying to find out if it is worth it.
Thanks

widmark, I suggest you take a look at this thread. Early 2010s had an issue with iPods. The top song would play while scrolling through a list. Lexus issued a TSB to fix it. While I'm not sure if it'll help with your iPhone, it's worth a shot. And yes, there is a way to check which firmware version you have. I think instructions are linked in the thread above.
