What do you guys think about having two LoJacks on the car?? Overboard??

 

no need for 2 lojacks! just get one and lower your insurance premiums. They install it in one of a few "secret" locations so you dont even know where it is..

 

Given the GPS stuff and teleaid, is a Lojack even needed?

 

I was told awhile back that the GPS (hence Tele-Aid) can be overridden by simply putting the car inside a metal trailer. The GPS signal would simply be attenuated and disappear from the TeleAid system.

For $700, I think it's a good piece-of-mind, no?

I am also going to have clear-bra installed next weekend, but that's another story. I don't like rock chips, especially on a black car. The clear bra will be installed on the entire front end, a-pillar, front lights, roof line, and gas tank cover.

 

i would strongly suggest getting LoJack. your dealer should give you a good deal, i believe we payed 500 for a lifetime. also, you can put foil over the antenna, and tele-aid wont work.

 

Am I the only one who thinks that having some one splice into the delicate electronics of an E55 is not such a great idea?

 

I got LoJack too----one's enough--a piece of mind thing--no problems with the electronics.

--The clear bra is great---I had mine installed 2 days after I got the car--really does a great job protecting from rock chips---not the big stuff--but the daily sand blasting from driving on freeways.

 

Hmm. I don't think it's different from having someone adding a changer, a built-in radar, or lighted sills in terms of splicing wires.

 

I don't know how LoJac is installed but if its that easy, then couldn't they just unplug the battery to defeat it?

 

no, they can put in multiple places, they dont tell the owner, or anyone. if you mean the car battery...it is not connected to it, it has its own battery. so even if the car is off, they can send the slient signal

 

Well, if placing the car inside a metal trailer can "stop" GPS signals from going to and from the car ... as I understand it, Lojack also uses radio signals, and as such, a metal trailer should be able to defeat that as well, no? On the other hand, if you feel it's worth it to spend $700, redundancy is always (well, nearly always) a good thing in auto-security.

 

GPS uses high frequency signals, which can easily be attenuated. Radio frequencies are much lower frequencies which contain more energy and are harder to attenuate.

Provided (and I have to confirm this) that LoJack uses lower, radio frequencies, then it will be difficult to attenuate/block.

For the sake of paranoia, if the one and only one LoJack unit fails, I guess I'm hoping that there'd be a back-up system or something.

Maybe I can just take the fact that it will fail, and then I will just get a new car instead of recovering a beat-up stolen car.

I suppose I could spend that extra $700 for a RENNtech ECU reprogram.

 

GPS is just a signal from satellites, the gps reciever on Teleaid just does that, recieve, it transmits via analog cellular phone signals. I don't see how Lojack is any different. It its in a metal container, neither Lojack nor Teleaid will recieve the gps signals.

 

Arnee, you wouldn't happen to be in So Cal would you? I have been searching for a clear bra installer, but can't seem to get any info.

 

Yes, I am in SoCal. I found this place that does high-end cars and have done W211 E55s 2 or 3 times.

The kick is it's in San Diego. I'm driving down there in a couple of weekends to get it done. They said it should take a good half a day for everything (I want extra coverage on special places )

Anyway, here's the website: http://www.mishield.com/ and ask for Bill.

edit: This is the only place I've found that have done W211's so I'm going with them. I haven't found any other ones here in SoCal that have done W211's.

 

Thanks Arnee I am in that area quite a bit, so its no prob. I'll give them a call when I get back in town. Thanks again.

 

Lojack works like a radio homing beacon, just directional. GPS based Teleaid needs line of sight to work and cel phone triangulation systems have the occasional weak signal problems, but both can pinpoint a location.

Lojack does work in a container. It picked up a stolen car off the coast heading to South America,
