I had a touch pro (AT&T) with custom energy rom installed, and was able to get it to work with my X910bt. You can pair 2 ways, from the phone or from the head unit. I dont remember which way I got it to work, but I know if I tried to pair the other way, I did have issues.
If you are currently pairing from the head unit, try pairing from the phone instead, and I can almost guarentee it will fix your issue. (or vice versa)
