Well i found this when I paired my DX to my headunit the droid x supports sms via bluetooth through Kenwood headunit. No dobt that others will work if the headunit supports it, Ive read through kenwoods sms compatible list and almost none in the US supported tis till now. Thank you MOTOROLA!!!! My only gripe about motorola/android bluetooth stack is when I end a call about 10 seconds later it disconnects from my headunit and takes another 10 seconds to reconnect. Its not a kenwood issue its a moto/droid issue as my Droid did this also but every blackberry and dumbphone wold not do this. For those who are wondering im using Kenwood DNX5120 with KCA-BT200 bluetooth module.
