Hey alex,
Well I might be able to give you that smile you want for the day haha. I will try answer every question now.
- which head unit has the best iPad remote app?
There is one in halfords on offer atm 50% off i cant find link online i will look in store tomorrow!, and let you know
- can the head unit also skip tracks on the iPad, i.e. from the steering wheel control?
Yes it can, The head unit has a patch lead so all your steering wheel controls work, If you volume up, Skip, Pause it will do all of this on the ipad itself!.
and probably most importantly,
- where can the iPad get its music from? I have all my music on my iPhone (for example), but an iPad seemingly wouldn't have access to that except over the Internet using iTunes Match, which would be an unrealistic amount of mobile data use.
I want to do this to!, there are quite a few apps that im going to be testing which enable you to play the songs on your iPhone via bluetooth or wifi to the iPad and you control all the songs via the iPad when the songs are actually on your phone!.
Im waiting for my primer to set so i can wet send my holder and then i will upload some pics. Its looking really good and flush and holds in with the smart magent which is welded into the fibreglass to get the ipad out you push the bottom of the screen and the top flicks forward off the magnets and you can take the ipad out!.
I really would reccomend it to any one its amazing. I will update this better later tonight when i have some more infomation for you man
Cheers adam
