This support document describes what bluetooth profiles the iPhone supports http://support.apple.com/kb/HT3647. I'm not sure the iPHone supports what you are trying to do. Compare the profile in the support document and check with Chrysler and see if this is what the Jeep uses for this task.
Yes MAP is support by apple, but no Chrysler does not appear to support Apple IOS MAP, but for some reason, Android, Microsoft Phone OS works fine. HMMM take that for what its worth, I would say IMO that Apple MAP is not standard in some way. Next question does this work in other manufacture cars, HMMM not seen it working anywhere.
