Hello all! Bought a 2009 TL and have no idea what this aftermarket antenna is....Remote start/aftermarket alarm? There is also a toggle wired in hidden under the drivers footwell compartment behind the plastic cover. Car only came with OEM key fobs so not too sure...Any help/expertise is appreciated!

 

Looks to be for an aftermarket remote start

 

Exactly!

 

Or a remote if-you-don't-pay-your-car-loan immobilizer from a buy here pay here lot so the repo man can easily take it!

 

Ok that's what I was leaning towards.. Since I don't have the key fob for it; it's pretty much useless eh lol

 

Some remote start systems are able to utilize the OEM keyfobs
