The Rockmars is just a re-branding. The shopkeeper was not calling Rockmars, the Rockmars...it was not even in Rockmars packing. They were calling it old SATNAV, old DVD and new DVD for Civic dash (A) These chines stuff is confusing...
This "new DVD" might be made for some other country:-#
I think I was careful, and used "new in-dash thing" :-#
Anyways I think its not worth it....I am sticking to my plan...after getting clockspring from @zunny brother; I will wait till Eid and if in mean time if we able to source the unit that Atla$ is giving; will prefer it; else will simply seek the help of @rizwan400 brother and get the audio controls configured with Kenwood
