Query: slow navi, bogus Live Traffic

I wrote a very good review for this device 2 weeks after I used it. Now I regreted like hell. This device is too slow in finding satellite (like 2 mins sometimes). Also, the device will tell you the address you entered is to a unreachable destination when I entered to go back my home!! The deadliest, the whole purpose that i bought this one was due to the Live Traffic Update service, after 3 mo of trial period, you will find out that the company don't have contract with TMC (live traffic provider) to let you subscribe. it's B8ll Sh8t.
