radio interfernce with trinity plugged in

[danddmodsandrods]

Good morning gentlemen. todays question is this: i have a 2005 for f250 that in just installed a trinity tuner in and the issue i am having is that with the tuner plugged in the radio looses all its stations. as soon as i unplug the trinity the radio comes back on. have you found a fix for this yet. it doesn't matter where i move the trinity to within the cab, it still interferes with the radio. is this a trinity issue or a factory radio issue, like not being grounded correctly? please let me know what i can do. i have alrready tried shielding the harness and that doesn't work. any ideas on your end?
thank you

There may be some interference from the unit, others who have reported this have had good luck simply moving it to a different location. Is it an aftermarket stereo or stock?

STOCK STEREO AS I MENTIONED. HAVE MOVED IT EVERYWHERE IN THE CAB AND IT STILL INTERFERES. WHAT NEXT GUYS?

It may be the cable, I dont have a solution beyond relocating things to be honest, but its not something I have ever seen or heard of on a 6.0 Ford.
