Coyote: SAV null and void RELIABILITY

I just bought a Coyote touch case and a Bluetooth headset Twins.
The Bluetooth headset works do not.The Twins works fine with another Coyote, so this is my camera not working.
After 15 calls for service, I see the TOTAL LACK counselors, and impossible to have a qualified tehnicien, it goes:
1-You bought your Coyote Renault boutique, and many see the SAV Renault,
or: Wait Sir, I'm going to see music and I hang it!.
2-I realize that the purchase date is improper rangeland in choosing "HISTORICAL-TICKET" and impossible to change this date, it eats me 10 month warranty.
3-I realize that the version of Coyote my software is not Bluetooth, while there has Bluetooth logo on the packaging box and user manual shows how to turn on Bluetooth.
4-On sends me another box with ANOTHER VERSION SOFTWARE, Bluetooth works, but there is no protective film on the screen and the casing is scratched at the back of the unit.
5-I had a flash of 20:30 to Poey Lescar- 64-, and even 40 Coyotes before me, NO SIGNAL ??? E 45 and 1 point less!
6-The fixed radar Habas -40 -, commissioned in 2005, is not detected by the Coyote ???
7-The fixed radar Cubzac Les Ponts-33- is not detected by the Coyote ??? 45E and 1 point less!
So I have only one advice for you ..............
