having dismantled and put together a saloon interior 3 times a coupe 2 times i can tell you its not easy as some cars out there but its still pretty straight forward...
i guess you have a saloon since you said 318i ?
the plastic along the door pops out so does the rear bench... run the cable to the radio under the carpet at the glove box and through the dash...
the power wire that runs to the battery is goin to create you a bit of trouble tho... what i did was removed the battery and the top of the fuse box and ran the cable in where there a hundred other cables going into the car... you'll know what i mean when you see it....
anyway i am way too lazy to post pics or do a full write up... __________________ .............................
