Temp global mod is Magnetron, he might be able to change the poll for you.
I think if you're going to ask which "devices" (it might already have poll for that), it should be out of NNG section. The devices choice should be
1. Phone
2. PNA
3. 2DIN
4. Other
or you can ask which OS
1. Android
2. iOS
3. Windows
4. Other
Notice I did not mention the word "best" because it will open the poll to a discussion. If that is your intent, then you might want to mention to the users to tell why it is "best" for them. And stick with facts rather than opinions.
