Which 2 Way Systems / LCD Systems?

There have been alot of threads started in the past couple of months in regards to LCD or 2 way alarm, remote start and combo units. Please take this opportunity to vote on the system that you have had the best performance, reliability, installation time as well as other pro's and con's and list them in your response so that other member's can see what is available out on the market. Thanks and Shiver Git !!! }:) 

BTW: This IS NOT a thread for anyone to start bashing other companies. If you had bad luck with one certain company please do not use this thread to vent your frustrations. ONLY the systems you would suggest to other member's are to be posted with pro's and con's on that system .

DEI looks like its pulling away in the polls

I myself would have to go with the audiovox 996C. I had previously installed a DEI 790 in my 95 Formua and the range on the thing was terrible. I thought maybe I had a def unit or a bad antenna or maybe a bad ground (that believe it or not does effect range) so i swapped everything out, wires and everything, for a new one but I still had terrible range. My shop also stocks audiovox alarms so i switched to the 996C just to see how that one was. The 996C was by far the best one I've ever used. The range was at least a good 200-300 feet longer than the 790 and had a lot more/better features. The 996C has a little bigger brain than the 790 but doesnt have the seprate relay bank for the RS, all the relays are contained in the brain so you dont have to find two places to put the components. The shock sensor has little tabs on it so you actually have something to zip-tie or screw the shock sensor down with as with the 790 the shock sensor is just a little plastic bubble that is hard to keep a zip-tie from sliding off of. The 996C has a built in thermometor(sp) this way by hitting a button on the remote the temp inside your car will be displayed on the remote of the 996C in deg. C or deg F your choice, the 790 does not have this feature. Another advantage is that you can set the 996C to start the car if it drops below a certain temp. and run for a preset time to keep the fluids from freezing in extreme cold. The antenna for the 790 looks something that belongs on the top of a tv to pick up sations from mars but the antenna on the 996c is smaller than most regualr antennas. Its about the size of a remote with a little nub sticking out of it total of about 2" long where the 790 antenna is about a foot long. You can page the remote from your car with the 996C by pushing the program button I havent checked but i dont believe this is an option with the 790 (convient when you lose your keys). Most of all beyond all the better options and functions the remote for the 996C looks sooooooooooooooo much nicer than that on the 790. The 996C remote is all silver with a little black antenna on it  with either a green or orange back lit display  (not an option on one remote just you can get a remote with either color). It looks like a mini cell phone and is a good convo starter when people ask if its a cell (happens alot). The remote for the 790 is very boxy and the color isnt the most appealing.

I'm not trying to put down the 790 its a good alarm/rs but the 996C by audiovox is just all around better. The only complaint about the audiovox is the programming. You cannot use a bitwriter on it (obviously, its not a DEI product) and the menus are not the simplest things to navigate through. If you have the manual in front of you that shows you how do do the programing it is relatively easy but not something you can memorize like with the 790. So all in all the only thing that the 790 has over the 996C is programing which you have to do once.

Hope this helps with your purchase decision.

I also have been doing the same (about 4 starters a day  for the last 4 months) and i do agree with ravendarat that DEI does make a great remote starter. The 369D is the one my shop sells the most of and it really hasnt given me any problems at all but the question in hand is the 2-way paging systems. In my experience, reliability wise both the audiovox and DEI 2-way paging systems rarely give me any problems what so ever. If there is any question about the reliablity of the audiovox though it does come with a full lifetime warranty.  

Definately have to agree with elpuma817, the new DEI relay module is great. Less than half the size of the original relay bank and has the starter kill relay built right it.....very cool.

my second look opinon of the 554r has improved, the system is loaded with options to fit almost any need/vehicle you may have, but your gonna need more relays, and take my advice and let the dealer install it cause I did not have an electrical schematic for my car(my error), 2 days later and everything is installed except the door trigger circuit that after going thru EVERY wire at the drivers kick panel while opening and closing the switch (I've only had the car a month so I am not familiar with it yet, and no its not the black w/lt. blue trace wire!) and the remote sttart needs another relay to simulate pressing the brake pedal to engage the starter, I asked dei NICELY for help/ access to info at their techs only site but being a paying customer with an applied science in automotive technology and 20+yrs expierience as a service tech/installer was not good enough, (a**holes) not even the offer of a non-disclosure agreement was refused, makes me wonder what they dont want anyone knowing like the fact that dei has bought out most brands of car alarms coming close to a monopoly of the industry the fall of customer service and competition gets us the kind of "help" one can expect from "Im the only source so take it or leave it" companies,   the alarm is great, the company sucks $&@!

PS the remote relay bank uses too small a gauge wiring to power the starter for long let alone the heater& defroster even the wires from my key switch are larger so be careful unless you like red lights and lotsa water and walking
