Personally, I know it's possible...

Started driving with a box type and yung mga sunod kong cars pinalitan ko head unit... Pero nung nag work na ako, sa dealership pa lang pinapa-upgrade ko na yung HU...

And the City's touchscreen stock HU is a normal double din...

It's basically power+speakers (wala naman controls yung stearing ng Vios J)

Kaya lang... mahirap pilitin and technician na ayaw magtrabaho...

Try ko sa smaller shops outside Banawe.
