Right, I understand that... But what I'm trying to do is not just stick a DVD in and upgrade the OS, I'm trying to get a Gen 4 (or 5, but probably 4) computer with Gen 4 discs... Basically replacing the whole system without having to buy a new car.

There are a few hacks I would like to perform to my 2004 RX330. I think I have most of them figured out, but the one I can't seem to get is the v3 to v4 navigration upgrade. As I understand it I can buy a $300.00 DVD set and get the latest streets and whatnot, but I'll still be stuck with the v3 operating system. I really like the v4 look, feel and features. The console looks identical between v3 and v4 and when I think about it the actual nav computer is probably the only item I would need to upgrade (plus discs for v4) to get the newer software to run in my 330... But I'm making a lot of assumptions on connections, interfaces and whatnot. So my question is, has anyone been able to upgrade from a v3 nav to a v4 in a 330? Has anyone even tried? In case anyone is wondering, other hacks I would like to implement are: *1000watt inveter directly battery connected (in such a way that it does not drain when system off) *XM and iPod integration direct into stereo system *MacMini hack that was applied to Toyota Prius *Find a hack to permantly disable the 'no nav input while driving' problem A fun few projects for the summer... if it ever cools off... Thanks for any info, B

I had the exact same problem on a 2004 RX330... The sad thing is that because of this I'm thinking I may not purchase another Lexus (was thinking about an '07 LS). The lack of protection for the condensor is a bad design in my opinion. This is fine, I'll pay the damages (and I did), but it put a bitter taste in my mouth. A bad design from Lexus cost me about $800.00 in repairs. Bad PR move on their part, in my humble opinion. That's the beauty of choice though. One vendor *BLEEP*es me off, I can simply pick up and move to another.
