I purchased the D99 for the E46 from Jeff. My problem is that I purchased a new phone that only creates an ad-hoc hotspot. The D99 won't connect to it. I am not getting another phone, so my next option is to switch out the Dynavin unit with the windows unit. If someone wants this unit in perfect condition, please let me know. All I want need is for you to purchase the windows unit from Jeff and I will swap my unit with your unit.
