Hi guys,
I just picked up an 2004 Lexus RX that comes with Navigation, but I really don't like the screen. I am wondering is it possible to change it to a Generation 4 or Generation 5 system for the right price?

thanks
Adam

Not for the "right price." Surely it could be done for "a price," but the cost of changing out the systems is not commensurate with the relatively marginal improvements.
If you really "don't like" the screen, your best bet is to forget about it, use it anyway, and find comfort in knowing that your next car will have a better screen.

What about upgrading the ECU DVD player? I heard others have upgraded their generation 3 ECU to a generation 4 ECU, I am wondering if that is the same play and plug for the Rx?

I have a Gen 3 in one of my cars and a Gen 4 in another (which allows me to use the same DVD in both), and although the Gen 4 has a few extra features that the other lacks, I certainly would not spend a lot of time or money to upgrade. Even if you do, you will still have the same POI and map data, and the same screen. You will get a few extra icons, though.

MrBruin09

Are you sure about the screen not changing?

This member with from a generation 2 to a generation 4 and his screen looks totally different, but I can be wrong.

ok.. someone jump to GEN5 and see if that works...

the map data for Gen 3 goes up to like 2 million POIs, while the Gen 4 and 5 have up to 8 million POIs. One thing that I don't like about the Gen 3 on my wife's RX is that it doesn't even have simple things like post offices and movie theatres. The Gen 5 on my GX seems to have everything.

I may have to consider this upgrade if it is as simple as it seems.

I just wanted to say that I did this upgrade with my wife's RX. It is truly plug and play. Works great and seems much faster than the Gen 3. Also, the # of POIs is much higher -- has as many as the Gen 5. Can even search via phone # which I like a lot.

Did you simply pull out the Gen 3 unit, put in a Gen 4 unit, connect it and power it on?

sickntired

yes. Well, also put in the new 9.1 disc as the one it came with was 4.1

Gen4 can swap out with a Gen5 but need to make a special harness
the upgrade cost is around $1500 with your gen4 screen sent in.
the $1500 also includes latest maps and ability to control audio via the screen

MrBruin09

Look like I might need to start saving up for this


Mowmow do we have get a new 9 inch screen with this option?

sickntired

Does anyone know if it is possible to upgrade the in-dash CD player that is in the 2004 to the one that is in the 2007-2009 RX 350s? I would need the one that goes with the Mark Levinson system. Would the amp also need to be changed? How much would an upgrade like this cost?

mowmow

Whatever Gen 5 screen size is. I need to save up too. I don't know if 9" screen can fit the current spot my Gen 4 which is 6.5" screen

mowmow

I was wondering this when i first got my RX400h but the cost is just way too much and the end result is not as impressive as the other models of Lexus are so I gave that idea up.
