Hi guy, where does one buy the updated disk? Thank you! have any one tried to buy it from ebay, I mean if they aren't new, there is a possibility the disk will stop working again.

 

Having this issue now on my 2006 TL. Cleaning disc didn't help. Running diagnostics and the ECU is fine. The Navi System Link has been detecting FI-ECU and Meter for over an hour. When I turn the car on, it does "downloading software, please wait". Then asks for my Navi lock code. Then looks for GPS signal for a few minutes & will work. Bit then the voice is super loud and staticky.

I called Alpine and said it needs to be serviced in house & the cost is now $470 with a 3-4 week wait.
