Sorry to hear about the damage..Looks costly
.
Ok, there are several reasons on why you may have experienced those glitches. I had experienced them before as well. I'll just list out those possible ones here.
1) Accidentily switching off of the transmitter ( i kena this before)
2) Battery died on receiver or transmitter (I kena this before as well) . Or could be just for a few seconds due to bad connections.
3) Frayed receiver attenna and it touches your carbon deck.
4) Cracked crystal (due to previous langgar_with_wall..
)
5) well, there was somebody else nearby on the same frequency.
Try out your electronics on another car (if you have another, or can pinjam from a friend). See whether the glitches could be repeated again . If it could, then maybe there is something wrong with the electronics. Else it just means it was 1 time event and probably may not happen again.
