I recently got myself a Sony MEX-R1 from Pixmania. For £190 it is amazing value. Though it will play DVDs (i.e. video) I got it for its giga mp3 capability. So, I installed it without a screen. It would appear that most functions work fine without the screen. But I have noticed the following things that really bug me (already). * Start-up time. Seems to read the entire disc before it'll start playing (with MP3 discs), this can take minutes! * Can't set the time / doesn't pick the time up from RDS. * Can't disable demo mode without the use of the screen/remote control. * When the ignition is turned off, it doesn't remember if "attenuation" was on when the ignition is turned back on. * Doesn't remember that it was playing a disc when ignition power is restored (i.e. it comes back in the "off" state and you have to press play) If anyone knows what I'm doing wrong, or if there are setting available using the screen - then I'd like to know. Apart from my issues above, this is a fantastic player and amazing value.
