I have a Omega Link remote start system that will work with E89 and E9x (most 2005 + models). The module model is Omega OL-RS-BM1, retail for around $380-ish selling for $330.
Also have a GPS Carlink Module that still have GPS and remote start subscription till Feb, 2017. Module by itself is $250-ish, selling for $240 with more than 6 months of subscription left($100/year).
Get both for $500 firm.
Text me @ 3217202304 if you have any question.
