More Cascadia woes

i have 13 Cascadia and went with the bird perch works good I ran the coax myself not hard to do just pull the mirror back some so you can get the coax through and in to the inside of the door remove door panel and there is a rubber grommet on the firewall that you can remove to bring it into the back side of the dash I did it that way cause I don't like my coax running out the door jam or from the hood like I see most have done cleaner look

 

Since this anomaly occurred after the servicing of your APU (And it involved the alternator on the unit) something tells me that possibly one of the techs may have introduced something into the electrical system due to negligence/by accident, such as a spike, short, surge, unintentional or improper grounding during its removal etc. and may have made its way into the boards. Just a hunch.

 

Hope you get your problem resumed driver you have pumped a lot of money into that radio

 

Have you tried mounting the radio above the windshield there are compartments there' you would need to run extra cable I guess just out of curiosity do you shoot skip or just stick to am

 

you got whine from the new alternator on the apu, feeding into the electrical system, sounds like moving it away from the QUALCOMM may help and you need a ground loop isolator

 

Any time a shop is going to work on the truck, ALWAYS unplug your radio. In a Cascadia on the right side of the dash, remove the top cover from the dash, the fuse box is there, on the right side of the fuse box is 3 heavy connections, 1 side hot always, 1 is switched ign only, and 1 is ign/acc. You can ground to the steel sheet metal directly to the with a 1/4 sheet metal screw and a external/internal lockwasher.

Whn they disconnect and reconnect the batteries this generates a very high voltage spike traveling thru the electrical system. More than likely blew the caps and diodes in the radio, maybe a few chips as well. Stop throwing good money after bad and replace the radio. Odds are this is the eventual answer Good luck with it..

 

Why not just get it fixed???
