r8 suction cups failing

ive only had my r8 for a few months now and today the suction cups failed in the middle of the road just from me pressing the volume up button. probably because of the sudden change in weather as they seemed decently strong before. no matter what i couldn't get it to stick back. once i go home ill see if i cant clean them and the windshield off and run the defroster to warm everything up and hopefully get it to stick again. but even if the does work this just happen again as its going to stay freezing here. does anyone have stronger replacement ones or any good workarounds?
