2007 bmw 328xi, remote start

  we did an 07 5 series with a smart key a month ago.  we used fortins bmw-int1 module (msrp of $250!!!).  i dunno if it will work on the 3 seres, but i think it might.  however, the first one we received was defective.  the second one worked, but the car shut down during "key takeover" and had to be restarted manually before driving away.   we are waiting for the cust to come back to see if we cant figure out how to make it work correctly.  primarily, we use idatalinks when we can- we have ahd very good luck with almost all of them, and tech support is great.   good luck(4)g5-1244, (4)gtr12, (2)ppipcx2400, (1)pcx4125, (1)pc4800.2, (3) pair mb quart 6.5"Q, (4)optimas, alumapro (1)5 and(1)15 farad cap, premier deh-p860mp, pioneer xm -dual H.O. alternators

yes I just did a 2007 328xi auto trans.I used a compustar with a cansl2 and bmw-int1 .both thes modules are from fortin .thinking from memory the basics are compustar power and ground to the car ,ign ties in with the modules,the cansl2 is wired to the remote start and the bmw-int1 uses a ribbon cable to tie in to the push button and a couple of  wires to tie in the brake then has a databus line to the remote start. this was the first so took a little time but the directions were very good and self explanatory.this one as long as customer unloced the vehicle with remote and placed the fob in the slot takeover is no problem.
