Sat Nav - How-To And Determining If Your Have Dvd Or Hdd Based?

Recommended Posts

Hi all,

I have a 2012 IS and I've baulked at the price of an update from the dealer - but it seems there are alternatives.

Some quick questions about updating the maps:

1. how can I confirm if a DVD update will work for me?

2. what's the method for updating it?

3. is it just a standard iso and are the online vendors reputable?

1. Have a look at this: http://au.lexusownersclub.com/forums/topic/8170-howto-change-your-maps-dvd/

If you can't see the two tiny holes on your dashboard, or you open it and don't see a DVD slot, then you have a HDD-based map system.

2. If it's DVD-based, refer to the above link. Otherwise, refer to your Owners Manual.

3. It's a standard ISO, but some copied disc formats may work better than others.

Whereismaps.com sells genuine maps for less than the dealers, at $295.

Yes I have a 2010 IS250, usually if you have a screen you have a DVD in there, I have updated toWhereis - Denso V18 and usually skip the V19 and will now upgrade to V20 (Release date May 2014) BUT if you have a 2012 you probably have V19 so I would wait for V21. REASON: The difference between V19 and V20 is not noticeable. I think you can get a genuine Version 20 from Whereis for $295.00. In fact I may wait for V21 if I am going to spend that money.

Why pay that outrageous price every year for those discs, and they can't keep up with all the tunnels being built in Brisbane?

There is an app that I run in iPad - it is called Metroview, updates free for life and often too

It is an Aussie GPS and it is awesome, only $24, never use the Lexus GPS again

But hey, Google for iTunes discounts, right now Coles have gift cards for 20% off

And at Harvey Norman, get 2 x $20 cards for 25% off

Can't beat that :)

Moderator can delete if they think I'm selling but I'm not, I just like the product
