2012 Entune touch screen head unit into regular head unit

Right now i have the stock non touch screen 2012 head unit. I wanted to buy someones take off entune HU that has GPS and use it in place of my head unit now. Would this be possible? I understand that if i want better sound i shouldn't replace the stock 2012 head unit with the entune version but all i wanted to do was add the touch screen capabilities that comes with apps and maps and such but keep the stock look. Would this be plug in play besides the GPS? I dont have JBL so id need the non JBL entune version.

 

you wont have gps unless you run the wiring and have the antenna also...just sayin.. way better to run a ftermarket system such as samsung or poineer

 

but theoretically if i ran the stock entune head unit would it be plug and play besides the GPS? im looking to keep stock look

 

WELL GO FOR IT!

 

I do have an oem toyota antenna if you like. I would just need to know the connector style if its square or round.
