GM has some parts that if installed at a dealer, it comes with lifetime warranty. look for a -W- or a * in the part number description.The stealership would charge $275 for their AC Delco.
Is that one of those repeaters with an antenna inside?
we've got a cell repeater out at the office, had it for much of the last decade now, just the basic plastic box antenna on it, not a super pointy one like that, it was rendered basically pointless except for guest's once everyone in the office upgraded to phones that support wifi calling, we now have cell coverage over the whole building, not the one room.
I'm looking for something similar for the trailer. Being the (sometimes) cheap bastidge I am, my cell service is very cheap, relative to ATT / Vz (and works very well in the midwest / east, thank you).
