This is definitely related to the external air temperature and I find it very strange.
Is this just a poorly made unit, or would it be installed incorrectly, or is it normal for touchscreens to malfunction when it's colder than usual?
It is actually normal for touchscreens to malfunction under cold temperatures. You can check the operating specifications in your manual however, keep in mind that the operating temperature range specifies the extremes on each end. If you are nearing the lower limit you will start to lag, exhibit unusual behavior such as "sticky" commands, delays, etc.
Some of my old high-end Alpine decks would have the LCD displays move in "slow motion" when the temperatures are around/below zero (Celsius). Of course this stops happening a few minutes after I start driving because the cabin heats up and then there are no problems. It would only happen if the vehicle sat in the cold for a while.
Just as an example, people typically assume that their touchscreen phones work fine in the cold but they forget that their phone is not actually sitting out in the cold air. It is typically in your pocket, or shielded in your bag. Leave your iPhone at -5C/-10C for about 20-30 minutes and pick it up and see if it is as responsive as it should be. It almost certainly won't be. I'm just using this as an example since somebody above pointed out that the phones do not have an issue and that your unit is defective.
I'm telling you, check the operating temperatures, and if you are within 10C of the minimum you will likely have issues.Edited by dejanh - 12/11/12 at 9:42am
