WHY CAN NOT TRUST to COYOTE

I bought in 2010 Coyote Nav V2 with updated life for 300. Free Small problem: Coyote has all of a sudden finalized its updates without warning. The machine then becomes useless. I have called in vain for citing breach of contract. I sent a letter to which Coyote did not even respond. So if one day you have a problem, here is what you can expect. I therefore expressly recommends Coyote.
