The XM antenna needs to be relocated if you use the long Pioneer rack. You’ll get signal drop outs quite often with that hunk of metal right above the antenna. This bracket makes it easy: https://maximus-3.com/home/maximus-3-jl-satellite-antenna-relocation-bracket
I haven’t had any issues with the GPS antenna, but I don’t use it very often.
No wonder!!!!! I've been having bad signals ever since I installed mine. Is it easy to relocate?
Thanks for the advise!
