Hi,
It is any way for replacing old navigation TNS600 system with carputer and climate control for another new (china ect.) All-in-one (navigation,gps, BT, ect)?
(It hink that is big problem with integrated climate control). I can not find any url page with the project/DIY exchange old navigation/carputer system with a new one. Or ALL In One compatibile unit.
I have this system in car TLC120/2006/AT
Thanks
