What if you want to install the next year's version?

My current 2005 toyota has a map on DVD, and it's not got all the roads,
even the ones that existed then. A repacement DVD is 90+ dollars!
but mine is good. OTOH, one for 2011 is only $20, but I'm guessing it
won't work right??? And I don't know if it has many more roads or not.
Maybe it only has more recent stores.

And I don't see anything newer than 2011, so I figure they don't use
DVDs anymore. ??

I don't need navigation, only occasionally to know where I am.

If the GPS map on new radios isn't a lot better than what I have, I'd
rather save a couple hundred dollars and get a radio withou it.


It depends on the manufacturer. Most use either an SD card or a DVD to
update the maps in the on board system. You won't find one from the auto
manufacturer with actual current year maps though. For that you need to
update with the most current data from whoever they used for the map data.
For instance my Journey uses a UConnect system unit that runs Garmin
maps, I can update it using ONLY Garmin data, but I can get updates
directly through Garmin and add it through an SD or DVD for a lot less
than going to a dealer

The new Toyotas also use Garmin and an SD card for updates.

Read some of Micky's latest posts. It's not the GPS built into the car,
which is what I thought from his posts too.
It's a GPS map that's part of an aftermarket radio to be added. Or
maybe he already has it. Who knows. Brand unknown. Model unknown.
So much better to start 100 post threads speculating without knowing
WTF he has or plans to have, instead of Micky going to a website for
the few manufacturers that probably make one that fits his actual car.
I'm surprised he's still alive.
