Is your PFL an import?  The UK ones had a Sony WX-C570R head unit fitted at the port of entry.  When I still had that unit in my car I met one of the Portbury dock team who fitted them with the Thatcham alarms - car was at Haynes breakfast club and a conversation started!

It's a PFL. But I think that diagram is incorrect, at least for my car. The previous head unit only had CN700 plugged in and everything worked. The other 3 connectors were left unplugged (because there was no where to plug them in).

Could be incredibly wrong, but assuming facelift model, the headunit was used in other Toyotas.

Optional extras across other models would have included CD changers, an extremely primitive sat nav, and steering wheel controls.

So I replaced the stereo for the stock OEM one. As I put all the electrical connectors back in, one won't quite reach so I didn't bother forcing it. It's the small one with only 1 wire. What's it for? Everything appears to work without it but just wondered what it was for.

Aerial works. Illumination works.

got nice wheels too 

I saw this on YouTube a while back.
On FB, there is a chap who bought a rear cut with the Scooby engine in it. He is goinf to transfer to his car.

Maybe that's the car!

Hmmmm... less coincidence would make one a conspiracy theorist 

Just received a heads up from a JDM goodies seller in Japan with EU channels. A set of Volk CE28 for sale in the required size.
I know I have an open search request outstanding but still quite toodoodoo.

Very nice set but mán    prices. I do have the slush fund but it is a lót of money for under 1 kg/wheel.  The Prius callipers sure were a better deal.  Ánd the RPF1s look as good as it comes on the ZZW30.....
Yet; anyone on the market for Enkeis? 15" 7J  ET37  4,4 kg.  They don´t fit as cabin luggage, but you coúld enjoy a southern sun holiday and the dríve back or find a man with a van?

Got the car back from the local garage today - wheels and steering waaaay better.

I intend to email RRR middle of the week to confirm this saturday... if anyone is in the local and wishes to see and observe what actually happens on one of these sessions they are most welcome.

So pleased it lives on and you are enjoying it already   

Look forward to more reports and sideways photos!
