I just had the Continental Extreme Contact DWS tires installed Saturday and what a huge improvement compared to my Yokohama S Drive tires. She drives like the day I bought her. And I sent off for my free Nook as well!

You can find the used gen 4 or 5 systems on Ebay sometimes, but they are going for $500 and up. Others who changed from generation 2/3 systems, compared the gen 4 and 5 systems and have expressed that upgrading to a gen 5 system was not worth it for our year of SC430. There are those who have upgraded from a 2/3 system to a 4 system and have stated it was worth it. Those who still have the gen 2/3 systems really don't see that much of an improvement in software options between version 8 to version 10 either. I just purchased today software version 6.1 for my generation 2/3 system for $50.00 on Ebay. I am currently using version 2.1 which is the original nav disc from 2003, can't wait to get version 6.1 loaded.

For $12K they better throw in ALOT more than the offer to give you version 10.1 and to install it... from what I have read, installing it is very simple.

I am going to send you a pm with some more information.

Thanks Mark, I just phoned Sewell and the parts man Dan sounded knowledgeable... immediatedly explained a 2003 SC430 requires a Gen 2/3 disk, but he also added that a version 10.1 is available (dated Oct 2010) and it will work. His price is $200, but he also quickly added that if bought on-line, on the website, it will be cheaper. I am now trying to find out if it is available on the website. So far, all I see on the website is Gen 5 disks... a lot cheaper @ $92. By the way, my dealer quoted me $300. I am curious if I can find a complete Gen 5 Nav system in the junk yard... dealer also told me a new Gen 2/3 Nav system is $5K, but a new Gen 5 Nav system is $12K (but they will throw in the latest DVD too and they will also install it).

Hi zzjones, I have a 2003 SC430 as well with version 2.1 nav disk. Our year has a "Generation 2/3" model of the dvd/navigation player. I am pretty sure generation 4 or 5 will not work in our model year. When looking for an updated disc, make sure it is a generation 2/3 disc. You will see alot of used disks on Ebay or possibly Sewell Lexus in Texas usually sells the older version of nav disks for alot less then the newest 10.1 version. http://lexus.sewellparts.com/closeout.html

I have never ejected my disk yet, but thankfully it is easy to get to in the trunk. If you find an updated disk, it is just like installing software on a computer, eject the old disc and input the new one and the system installs the new software.

Hey guys quick question. I don't really know much about sound systems and was wondering if I can use 4 ohm speakers for the door speakers in my SC430. Both my front speakers are buzzing so my dad bought 2 Alpine speakers. Will it work and if it does, will it drop the sound quality? Thanks!

here's the same speakers my dad bought

I don't think replacing 8ohm speakers with the 4ohm speakers is a good idea. I had the same issue when I bought my 2003 SC430. I have read on another forum that if you use the 4ohm speakers, you run the risk of burning up your amp. Buy the 6x9 to 6.5" speaker adapters from Ebay for around $10.00, then find some 8ohm 6.5" speakers. Try to find speakers that are 3" or less in depth so they fit the opening without obstructing the rolling down of your windows.

Here is the link to the speaker adapters:
