Map updates have gotten pretty cheap: http://www.lexusnavi...at_to_order.php

What you call "firmware" is usually part of the update. Updating your maps may not make those new roads show up - it can take from years to "never" for them the show - but an update should help quite a bit - especially for POI's - if the one you have is the original one.

Ok, thanks, so is it simply a new DVD and replacing the old one?

I guess with DVD-based models firmwares not updated, right?

PS. BTW, I find $169 for just a DVD with new maps a bit expensive, although not outragous...

We've been having problems with spongy and weak brakes on our RX350 for a couple of years, multiple visits to dealer hasn't resulted in any improvements, and they've done both pads, rotors, and it's still not great.

Symptom: There's just a lot of delay from applying the brakes for them to work and unless you slam, it will not stop, so it's kinda difficult to do a smooth, gradual stop.

Any ideas? Is it just the nature of this car? or it's something that can be updated? like pads? or fluid? etc...?

Thanks

Hi everyone,

What's the best way to update the maps on 2007 RX350? It is totally missing a lot of newer roads.

Also, has there been any firmware update? to improve functionality? Would dealers do those? and if so, is it free or you need to pay?

Thanks
