N3vem, Let know how it goes, I'm running a Uniden 396XT with remote head and a XPR5550, and switched to a standard remote head, both main chassis are mounted in the trunk, came out quite nice.
Having big time RF issues through the speaker system. Very annoying while in transmit. I found The Mytouch system appears to be always on, even with the radio off, and even with the (keyless) ignition switched completely off. I get RFI more on the low side 440-445 Mhz side than above 445. I found the only way to stop it, and shut the stereo down completely is to pull the dang radio fuse!
Yes, even with the stereo's amplifier fuse pulled the stereo speakers are still on! It uses them for chimes and warning sounds, as soon as a door opens. I may have to run a dang toggle switch to that fuse to do a real shutdown of the stereo system.
