Update on my DSRT 392's Radio/Uconnect issues ...

[RetiredFirefighter]

I had posted a thread on my ongoing electronics issues.
https://www.durangosrt.org/threads/what-is-it-with-vehicle-electronics-issues-these-days.15799/

A quick recap:

• Dealer replaced the infotainment screen after a software update permanently deleted Performance Pages/Drive Modes.
• The new radio fixed the PP/Drive Modes issue.
• Later on, the audible voice that comes in when the NAV or VR/Phone buttons are used was gone.
• Nav maps were also now stuck in Night Mode.

Current:

• I brought it back last week. Finding no error codes, the dealer contacted Dodge STAR techs for a fix.
• They gave me a rental car, as a portion of my vehicle's interior had been disassembled.
• During the week they tried the items STAR told them to check. No dice.
• They're returning my vehicle after doing an OEM factory reset on the radio/Uconnect.
• I was told not to program the radio in any way for 72 hours (no phone pairing, etc.).
• I am then to return to the dealer where they'll see what's what.
• If the voice is still missing, they'll contact STAR again and go from there.

Any ideas as to why the 72 hour wait on not programming my radio/info system?
(I was told I could still manually tune the radio to hear music, but that's it).
