I've just got a new car and attached the XR-CA370 to power - but I can not get any lights or anything on the display.
I have followed the connection guide from SONY and connected the black cable to earth and the red and yellow to the 12V+.
I have tried just the red to 12V+ and press reset, nothing.
Just the yellow to 12V+ and press reset, nothing.
AND both red and yellow to the 12V+ and press reset - NOTHING!

There is a wire that attaches to the radio that turns on the radio lights together with the park/running lights. You must've attached that wire to a full time power source if the running lights are on all the time, right after a radio install. Recheck your radio wiring.
Good news - they're adjustable. The radio is used to adjust the vehicle's chime level. To change the volume level of the chime, press and hold push-button 6 with the ignition on and the radio power off. The volume level will change from the normal level to loud, and LOUD will appear on the radio display. To change back to the default or normal setting, press and hold push-button 6 again. The volume level will change from the loud level to normal, and NORMAL will appear on the radio display.
Note: Each time the chime volume is changed, three chimes will sound to indicate the new volume selected.
It sounds like they messed up your installation. You can confirm their work by verifying that each wire was attached properly.

Illumination is the grey wire from the car to the orange with white stripe from the radio.
I suspect that the yellow wire from the car is not connected properly. When the orange wire (constant power from the car) is attached, but not the yellow wire you can insert and eject cds, but it will not turn on. Constant power is used for maintaining the clock and preset radio stations.
If everything looks correct, I would take your car back to the installer and have them correct the issue.
The first thing to check is the solder connections on the display itself. Look specifically at the connections on either end of the display. These are the supply pins. Also, I don't know if this model has an LCD display or LED. If LCD, then make sure that the back light is funtioning.
Keep us posted on what you find.
I am about to sell one on eBay - here are the connections from the installation paperwork and connector that I have:
Top row, left to right:
White - Front Left (+)
Green - Rear Left (+)
Purple - Rear Right (+)
Gray - Front Right (+)
Blue/White strip - AMP REMOTE (Max 0.3A)
Blue - ANT REM (Power Antennta Remote) (12V, Max 0.1A)
Red - Power (Accessory)
Black - Ground
Bottom Row, left ot right
White/Black - Front Left (-)
Green - Rear Left (-)
Purple - Rear Right (-)
Gray - Front Right (-)
Yellow - Power (Battery)
One of the BLANKs is for the "Light Blue - ATT (attenuation for car phone)", but it is unclear which one. This wire is not on my connection block...
The circular BUS line to the right of the terminal block is apparently for linking to a CD/MD unit (cable supplied with unit)
The Blue 3.5mm socket is for the RM-X45 Rotary Commander (which attaches to the indicator lever)
If there is no ACC power line in the car, do not connect the red lead.
Ensure the power select switch on the bottom of the unit is in the B position, then press the RESET button (behind the faceplate).
This means that the display will be off when the unit is not in use - avoiding a flat battery risk.
(Posn A is for normal use, with red line on ACC)
The RESET buttom should be pressed after installation, before initial use.
