John, I'm going to share my little story about refurbed radios....
As most of you know I work at a truck dealership and at times forget that the automotive business model is far from the heavy truck business model...for example it still blows my mind that you cannot get replacement certification labels for cars in the event of a drivers door replacement.
I order them all the time for customers that have worn the labels right off the door jambs. Many times large fleets will order them before putting the trucks up for sale where the existing one has faded....We verify a vin match and place the stickers on the truck to make sure there is no funny business.
Clean Idle Decals....same thing. Truck gets painted, door gets changed, washboy camps out on the sticker a whisker too long with the 2000 psi pressure washer, etc..
Radios, if one fails under warranty we go get a brand new matching radio and give it to the tech...
So with that being said I have a Chrysler T&C with a My Gig radio that also feeds a rear DVD screen. Just before the warranty was due to expire I asked for a replacement radio as the thing would bind up in cold weather, no screen, couldn't change the volume, shut if off or anything. Hope you left it on a good station on a -10 sunny morning...took a good two hours for it to thaw out and act right...
Did the deed and much to my surprise got a REFURBISHED My Gig. Hadn't given that possibility a thought, see above....
That was the biggest piece of electronic crap I have ever owned..screen started to fail, Sirius module went out, DVD would stick in the player and wouldn't eject it.
Finding Nemo was held hostage in it for over a year.....
So finally a couple years ago the screen went completely dark, the sh*t board that they didn't deal with during the refurbishment process finally blew it's guts..wife was tuning it by picking the next station, waiting for station identification, and then working her way to the station she wanted. I was going to get a cheap tuner from Crutchfield or something when I decided to give eBay a shot.
Found a takeout exact match on eBay with a 30 day money back guarantee, they wanted $100.00..offered $75.00 and they took it...freight paid.
Put that in and it works like a boss!! Better than the one that came in the van ever did. And impervious to cold as well.
So when I hear the word "Refurbished" I clench and recall the story above.....
IMHO keep what you have, Carplay binds up on the "Sync" in the company Ford I use especially after taking several calls in a row. Nature of the beast in my opinion. Unplug the cable and plug it back in. Good to go. I personally suspect the iPhone rather than the vehicle sound system.
If the rest of the functions work as they should I would let it be...
