I've been running with the Solo cordless on my other vehicles but want to go with something built in and less visible from the cops. My son had a system installed in his GT Mustang for around $800. Could have had the same system with "blockers" for $1,200. I've always been of the mind that these so-called "blockers" are a hoax. Could I get some opinions on the best installed systems for the GTO?
