I have a BMW Nav II which has died - as far as I can recall the screen was okay although has a screen protector stuck on it. No guarantees but you are welcome to it if you are ever passing or want to pay for postage.
Hi David, hope you're well. Did you replace it DIY? If so, was it straightforward? I've got the same problem with delamination on my NavII and I have a screen off a 2620 that I believe works, but I'm a little nervous doing it myself. Asgoo
IIRC the nav I is a 2610 which are prone to de lamination. I got an exchange recon from Garmin when mine delaminates. Git a map upgrade thrown in for free too.
