car stereo function strangely?

[irain84]

i have a nikkai stereo in my car, it worked fine but now it keeps on acting strange like no matter what button i press, it doesnt do the dedicated action but keeps on scrolling around these things,
NO CLOCK
NO ID3,

when i turn it off via power button, it turns off and starts immidiately after i depress the button.
it playes songs in memory card but when i try to change mode to CD or FM or AUX, instead of changing, it again says
NO CLOCK
NO ID3

i cannot forward, reverse the songs.
Volume also works strange,

Volume knob has got two options, which it is supposed to do,
if you revolve it normally, it effects volume,
if u press and revolve it, it goes to other functions like BASS, TREBBLE, but now, when i revove it normally, nothing happens, but when i press and revolve it, it effects the volume...
All the buttons are functioning but very strange.

I tried resetting the stereo, didnt work. i know its not damaged or something. what should i do?

If it is cold outside that could be the problem sometimes radios don't work right in cold. but otherwise it could need replacement
