Been using the RNS-E (LED 2012) since January and the Nav has been faultless. The disc hasn't been removed from the drive since I placed it in the drive when the RNS arrived. It was an eBay purchase - Pic of the disc below.
Just this last month it's started to fail reading the disc and produces the below error. Often I'll take the disc out, clean it, put it back in, the RNS will cycle a few restarts and the nav returns to full function. Other times it will keep cycling then reproduce the error message, sometimes mid journey which is A PITA to say the least.
I even placed the DVD contents onto my SD card before I realised it only reads from the DVD (from what I've found).
I've also tried two copies of the dual layer DVD disc, both by friends with dual layer DVD's and the two copies failed to read too (perhaps because it's copy of a copy...). The data on the original disc can clearly be read as it sometimes reads in the RNS-E DVD drive.
Despite the fact I can recover the Nav operation now and again, I can't have anything less than 100% availability in the Nav.
What are my options?
Appreciate your pointers.
