vios 04, PM me the price for gps/dvd vios 04 thanks

Chia, I installed your gps device last month. Do u all sell antenna to boost up the radio signals? cuz i feel that my vios antenna is not good enuf in receiving the radio freq. especially after i installed the gps device and the signals even weaker. Any solutions?

Oh ya, this is the vios 04 antenna problem, not the gps dvd player problem. Cuz before i install the device, my car radio signals also abit weak. This is a very good player. Chia after sales service is great. I am satisfied on it. 100& rating. U cant find dvd/gps player like this in the market with this price.
