I purchased a module I was told was required for my self install alarm for my automobile. Within 1 hr I learned they had mistakenly sold me the module and I did not require it for my model of vehicle.

I bout a $129.00 module I did not need and even though they persuaded me to buy it and inadvertently didn't need it they refuse to return my money, offer me store credit. Buyers beware there are probably better places to be buying your auto electronics from that are not so unscrupulous. read full review »
