I was a little reluctant as some of the reviews said it was difficult to get support.  I went online downloaded all of the documents, and then emailed support before buying to see if they would respond.  I always received emails back within the same day or next day.  Once I ordered I found it pretty easy to install, and the tools it came with will be helpful for some.  It installed with no problems, I did ask tech support some additional questions specific to my 2001 jeep and all were answered.  This has been great and have already started using it in the morning.  I am not sure on the remote reach, as I connected to my Viper Alarm also purchased on Amazon.  This is a great simple unit, although I do not have a factory alarm or transponder key to mess with.  I saved myself close to 300 on the install!  So far thumbs up!
