My search term skills must not be very good; I've been reading posts and possible solutions here for the last week. Thanks for the links!

Many of the threads I found have links to pages or files that no longer exist, or to suspect websites that want me to "sign up" in order to access downloadable files.

I've tried all the suggested sys.ex changes I've found on this forum regarding supported screen size/skin not found. I cannot find a sys.ex folder with m-settings, just the sys.ex under Devices: Android and the main sys.ex folder in iGO.

(I don't want people to think I'm a lazy forum user)

You'd think that in this day and age a simple software download from the vendor would detect settings and alert change the program to adapt automatically instead of leaving it a Scooby Doo mystery to be solved by the end user!
Ideally, I'd like to wipe all iGO from my radio and load an entirely new program on the GPS SD and instal/run it from there. It's just not happening for me. Not even downloading from Play Store directly to the unit via WiFi. I think I'll spring for an entirely new double DIN Android radio with 8.1 or better for $75 rather than keep running into brick walls trying to get iGO restored on my old 4.4. New radio won't have cd/dvd, but I've rarely used that function anyway!

Thanks for everyone's help, though!

Also, as per info I read in one of Boki_Srb's threads for iGO that is listed above; Primo doesn't work on anything below Oreo. which means it won't work on my radio (I tried anyway).
