Argh! I broke my RV760LMT

I picked up a used RV760LMT about two years ago and have been somewhat happy with it.  Oddly, a device costing over $500 (US) when released has been dropped like a hot potato by Garmin with fewer than 10 years of use.  Granted, I've only had the device since 2023, but the original owner paid plenty back in 2013 for the unit.  Lately, the device can't sit on the shelf for more than a few days without the unit's battery going dead.  Reviving it takes a few hours, so I decided to purchase a battery for the unit.  I've learned my lesson; Garmin devices are throw away items.  The assembly of the device makes it nearly impossible to replace the battery without damaging the display flex cable (which I did).  I have many years of experience repairing consumer electronics, but the RV760 is a non-repairable item if anything breaks on it.

Luckily for me, I found another RV760LMT on eBay for under $100, so I'll be back using this device again.  I'm reaching out on this forum for a few reasons:

  • The unit still works, minus the display (I can connect it to my PC and still do Basecamp mapping. 
    • Is there any repair sites in the US that will repair a broken RV760?
      • My base and display are still good, just the flex cable is toast.
      • Of course, the fee can't be more than $70 or so.
        • My assumption is no one will fix the device, but just asking.
    • If unrepairable, is there any value of just a working base unit with no display?
      • Thinking of eBay and would post for $25 or best offer?
        • Or is it just junk?

Back to Basecamp.  Why did Garmin abandon Basecamp back in '23?  It seems like a fairly decent program (with a steep learning curve).  Is Garmin still trying to market RV GPS devices or have they succumbed to the phone-based apps?  I've used Hammer and TruckMap in parallel with my RV760LMT, and all three more or less perform identically.  The Garmin device make pre-planning routes easier but now I'm contemplating dumping the Garmin after my new-to-me RV760 fails due to a bad battery.

I know this forum is about Basecamp and while this post isn't entirely about Basecamp, some aspects touch on it.  I'm looking to see constructive inputs on what's out there for decent, affordable RV GPS solutions.
