I was running Apex 1.3 and had my Droid X synced with my U-Connect head unit in my Jeep. It would tell me when I had a text message, read it to me and allow me to reply.
After installing the Liberty ROM I can sync and make phone call, use the phone-book etc. Everything is the exactly the same... except when I get a sms it does nothing. When I try to pull it by asking it to read old messages (which I could do before) it says no messages found. If I try to send it says failed.
It's making a different type of Bluetooth connection now is my only guess.
