IME Argos Bleak. Bought brand new from Analog Haven maybe 2 years ago, I have hardly patched it since, and it has barely seen any use. Comes with power cable and original stamped box it was shipped in. Module is flawless. I really don't want to let this go but my car is dead and I need cash. Thanks for looking!
