I have a 2005 LS430 - so when you update the disc, even in an older car, it shows the updated maps and icons like in a newer model GPS??????
Unfortunately not-still the same lame maps . All that is updated is your POI's such as new Starbuck's, restaurants etc. And by the way, I have the Ultimate Lockpick and 7.1. It does NOT allow override in the '05.
The new version is already out.. I got mine about a month ago.. They run about $270 I think. Install it yourself, do NOT let the dealer install it b/c they wanted to charge $40 to do it for you. All you do is put the disk in and then on the screen select the region you are in and it will automatically update for you... less than 1 minute of work but they want to charge $40...
I know everyone here is gen4/5 but I figured I would share my experience.
I actually just tried a "hybrid " disk and I got it to work the first time. I am running gen2/3 w/7.1 at this time with no issues. I burned it on a Memorex DVD+R DL using a Mac G4 tower and Toast.
I have gen. 2/3 with the OE 7.1 and the override works. You don't need to make a hybrid.
