Yaris Mk1 Navigation

[Farmerpug]

Sitting in my grandpas recently purchased 2005 yaris 1.0 VVTi t sprit i notice the radio has button saying navigation, my aunt also has a similarly aged yaris with the same layout, the button changes what the trip computer does. There are a number of other buttons with second function labels.

I understand that its cheaper for toyota to print the one batch of radios and not equip it with navigation, but this car is a 2005 T spirit (it seems to have most of the bits of kit a yaris could get) what models got navigation? Was navigation any good in these cars, can it be retrofitted?

There is no real need to install navigation into the car, but i am just interested to know more about it.

If I remember correctly from when I was getting my 2005 Corolla, the navigation was a very expensive option for all models, not standard on any. It was also done through the main stereo, so no colour or maps, just an arrow and spoken directions. No idea how you input addresses.

I looked at the SatNav. It was the TNS300 .. List price in 2005 was £1250 - yes really. (I have a 2005 Price list..)

They use a disk for maps iir and an updated disk is expensive. I use a Garmin which with free updates cost under £100...And far better.
