Ford Focus 2005 Stereo Upgrade Kit

[RonA]

I own a focus 2005 with a stereo like this one:

I got one of my low front door Speakers broken and decided to change the head unit along with the Speakers as it is really rubbish.

I'm new in Germany and I can't find any local kits for fitting the aftermarket units.

I want to install Hifonics TS-572 Titan Speakers

And Blaupunkt Melbourne 120

For a cheap alternative as I don't plan on keeping the car for much longer.

I would like to only use an SD card and USB stick for mp3 songs input without any extra buttons and a fair sound.

Where's a good place to get the kit I need to fit this headunit in the EU?

I need the keys, wiring adaptors, fuscia adaptor to DIN1 (with a tray), radio adaptor and steering wheel wiring adaptor and anything else I might have missed.

Is the combo I chose is recomended for the price level or are there better alternatives?

Thanks :-)
