Help: Pioneer head unit playing up?

[Rayage]

Hi,

I just recently got my car back from its 100,000km service and I noticed that my head unit (Pioneer DEH-7450MP) is doing something that it didn't do before the service:

The screen is an aqua-on-black display (the text is aqua). Every now and then the colours reverse (such that the text is black, and the backcolour is aqua). The head unit seems to work fine, but the random changes in colours flipping is distracting (while driving).

It slipped my mind to take the head unit off when I took the car in for servicing (the battery was disconnected at some stage during the service I'm sure). The service was done by my mechanic (someone I know and trust). I'm sure he took the negative terminal off the battery.

Never-the-less, I want to know if it's some setting I need to fix or is it something more terminal with the head unit?

it is probably a setting in the newer versions...just go through a section of the manual...

i know on my mates JVC i can change like 10 diff colours n stuff...

if it aint anywhere to be found, then go to where you bought it from n ask them , they SHOULD know

Thanx for the help dood.

I don't have the manual for this head unit cos it came with the car at purchase. Luckily I found the manual online, tho . Turns out it's some 'reverse' mode and all it does is it reverses the colours every 10 seconds. Bah..

That sounds familiar. I got the shits with my DEH-P6450 when I first got it with the same problem.
