SOURCE: 2004 Lexus RX330 Battery Replacement

You just had to disconnect the negative off the old battery first. Then you disconnect the positive and it happens to touch metal it won't short anything out. Make sure you can not wiggle the cables, that the connectors at the battery can't spin or move at all. Tighten them more if necessary, try to start it. Let me know if you still have problems.

I know there are aftermarket units but you will spend at least $1000 to get one.
However there is an all new RX for 2010, so, as the demand drops off for 2004-2009 accessories, the prices should begin to drop. I have also seen entire RX 330-350 units on ebay while searching for parts for my 2001 RX300.
I do know this is major work as I have seen the techs install an XM kit, ipod jacks and a rear DVD player as well.
They take out half the dash..... It is not a fast fix so at $100 an hour at the dealer, maybe a new aftermarket unit with far better resolution would be your best value.The 2004-2005 RX NAV was a bit grainy for my liking.......

replacing the headlights is easy. There is no need to adjust the afs, is is automatically done within the vehicle. Changing the bulbs doesn't affect the afs system at all.

SOURCE: My driver door on Lexus RX330 won't open

first thing you should do is try to have a shop open the door with a beak in kit. if they can't get the door open this way the door trim panel will have to be pryed off. it is difficult to do with the door closed but it can be done. the trim pane will probably be ruined during removal. once the trim panel is removed the door latch can be released from the inside.
