On iphone, go into Notification menu. Select Mail.
in Show option- select 5 or less
in your email accounts option- TURN ON Show in Lockscreen
bam, now you will see email.
but you will only see email that is on your lock screen, not older messages.
The idea is that you dont touch your phone while driving, and when a new email shows up it will appear on the idrive so you arent distracted and pick up the phone.
