But there are ways to upgrade to the 2011 disk and still be able to enter information on the fly... Check out the "Nav Hack " posts

^ There's also the Prestigious Society nav override module for those not comfortable splicing wires. It unlocks the nav and allows video playback while in motion (for those with Mark Levinson).

We also have a group buy going on right now for Club Lexus Members on the bypass. Please take a look here: https://www.clublexus.com/forums/clu...nd-nt3203.html

wonder how it works

Does this mean that all nav updates 11 and onwards will ONLY be done at the dealership???

I believe so.I'm having mine done this week or next.

Depends on the generation of nav you have and if it's the newest one updated via USB and dealer computer connection (yes, for now) or older via DVD (no, you can still update yourself).

^ If you have the HDD-based nav I believe so. You can still order the Nav DVD and self install for early MY 2IS's.

EDIT: What Dave said. He beat me to it.

2010 & 2011 are HDD based.

l-tuned parts.com is selling the 11.1 upgrade DVD for $155 with free shipping. Search for "nav".

Wish I could just port Google maps into my car Nav or utilize my cell phone's navi system / google maps. Then I would never have to upgrade it again!

Here it is

Don't forget about labor charge the dealership will charge (about 1 hour) for the install/upgrade to HDD-based nav systems.
