Hi there guys. Been a bit since I've used my Avic x710bt. I installed it in my 2010 Chevy Silverado and now my GPS is intermittently working. More to the notworking then working just curious what would cause that if it had worked before the only thing I did other than that period was a map update from eBay.

 

Any help would be greatly appreciated Kevin.

I installed the new tom tom cards and my GPS pioneer 910 BT no longer works the files seem corrupted and impossible to erase them. In addition I no longer have access with test mode

thank you for helping me
