if your installer has no idea of the electronics within your vehicle... would you want to have him install it? i wouldn't.

anyway the wrx doesn't have a transponder system. if you have the factory subaru security system you will either need to disconnect the subaru security harness or reconnect the starter wire loop.

otherwise the alarm is an easy install.

regarding the difference between A5 and a RSX3.5 is like night and day. The only RSX3.5 benefit is the 2 way lcd feature. Other than that the A5 has a lot more features and additional sensors such as tilt, prox & omni, blackjax, dual point immobilization, and other optional features such as the wireless immobilizer. you should go to and take a look at the product chart closer to see the real difference.

Since I never park my vehicle where I can't see or hear it... I'd go with the RSX3.5. The 2 way lcd is pretty cool. It's really up to you.

About the bypass, the installed said it was something i had one of my spare keys in at all times? i guess he thought my keys has a transponder or something. but the WRX doesnt have that? i dunno, im confused on this still.

so why would someone buy the RS3.5 over the avantguard? for the 2-way capability? It seems that the avantguard 5 and RS3.5 are both the same system. Except the avantguard has more sensors, and the RS3.5 has 2-way capability. Is this correct? what would you put on your car?

Is the 2-way even worth it? Hows the range in the real world?

PS - thanks for helping me out man.
