From what I gather (and I could be wrong) from reading various stuff on the V710 forums at HowardForums, the new 1.40OR firmware is not that new, but is exactly the same as the firmware beta update in December. SuperDave's firmware is based on the OR firmware, and unless u spend a lot of time moving files to and from the TF card, I don't think it will help us much.

I have the -552 module, and I was under the impression that is the 1st BMW BT module. Regardless, my V710 works well enough with the -552. Every now and then it continuously connects and disconnects from the car, but a quick turn off/on of the phone solves those issues. I'd love to get the caller ID on the Nav screen and the phone book to transfer. I am not holding my breath, and will keep an eye on the HF and BF forums to see if anyone has any updates.
