Good day. I am purchasing a vehicle with an AstroStart remote start and keyless entry unit (model TX0504 is the model number from the fob - remote control. I am picking up the vehicle later today and can get information right off the command module but I thought I would check ahead of time with the information I have). I would like users, instruction and possibly, installation instructions. Could you please provide assistance? My email is jforest1@shaw.ca. Thanking you in advance.
