Avensis Verso 2002 radio replacement? (+ few random questions)

[faire]

Hello everyone!
We bought ourselves our second Toyota and I have a couple of questions. Issue number one is radio - the CD player is not working and having our kids on board means we NEED music :). I know it is possible to buy a FM transmitter (phone => radio) but I was also considering replacing the whole unit with a tablet like this: https://www.aliexpress.com/item/Quad-Core-Android-5-1-Two-din-Car-DVD-Player-for-Toyota-Avensis-2002-2008-car/32765715701.html?spm=2114.search0104.8.4.BHOsPv . Questions are following:

1. Is the radio the same as with regular Avensis or are Verso's units anyhow different?

2. Will I lose the possibility to display the consumption, which is normally displayed on the radio display?

And few more random questions:

1. What are the optimal RPM for a 2.0 D4D?

2. Do you use any fuel additives?

3. I have heard that is is important to let the motor cool down after a drive - do you do that? How long time is appropriate?

 

Thanks for any answers!

You can also buy a SD/USB MP3 adapter that plugs into the rear CD changer port (5+7 pin) of your CD/radio - http://www.ebay.co.uk/itm/Toyota-Avensis-USB-adapter-interface-CTATYUSB001-car-AUX-SD-input-MP3-3-5mm-jack-/321963050868?epid=1804786429&hash=item4af67e4774:g:MTAAAOSwKtlWhR6C

It will be easier to fit with no wire cutting - just plug and play. That way you still have the display functions and steering controls work the music. Just get your music converted and transferred to memory stick/card, which is easy. That is how I have been playing my music, in the last 10 years or so. 

Your other qestions:

1. I don't own a diesel and what do you mean by optimal rpm?
2. Fuel additive question for the diesel owners. I don't use any with my petrol car.
3. For any turbo car, after any hard driving (going up a hill/towing/fast driving in lower gears , it has been said to let the engine idle for a few minutes before switching off. This protects the turbo.

Hope some of the answers help.
