Hi, I also have the Idatalink system. Yes there is a small antenna on top of windshield. But quite small.
I have a question about this system : mine doesnt work with 3 lock push button on OEM key even if wrote as function available on manuel and model I use.
Is it a mistake of programming by the guys who installed it ? Do I need to go back to see him ?
I didn't spend time on this issue because during summer I don't really need it so I don't keep with me remote key of Idatalink system. And is it really good to use OEM key : no feedback (two way) that 's engine started and range of OEM key is'nt good as the key of Idatalink system. The Idatalink key isn't so big to add with OEM key.
Another question : do you know if we can program on function 1/2/3 of Idatalink remote windshield defrost back and front, heated stearing or seat ?
Thanks, would it be possible for you to take a pic of the antenna?
