TV Box DVB-T and wireless rear cam for Caska 3635 Mazda 3

[mz3_1.6td]

Hello,
I had bought a Caska 3635G for my Mazda 3. i want to buy a Tv Box DVB-T. I view a Caska CA2518, but I don't know where I can buy it. Can I use a Eonon E0770 or another brand, is compatible with Caska 3635, or I must buy only Caska TVbox?
For dvb-t antenna where can you help me to climb on( under air opening plastic or another place which it can stay hidden)?
I want to buy a wireless rear cam, but can you advise me to find a ccd wireless rear cam? Can I buy only form Caska or anyone brand?
Thanks a lot.
Happy New 2012

we don't use dvb-t in north america. our mobile hd broadcasting standard is atsc-m and the first hand held devices just came into market last fall lol; no idea when atsc-m units for automotive application will come out. try asking on mazada3forums or a euro centric mobile a/v forum.
