after market head unit install questions

[griffadavi]

wanting to install an aftermarket head unit but everywhere i go says its not worth the hassle or simply cant be done and still being able to use heat/air etc (display screen). Does anyone have any info/recommendations or can point me in the right directions

And your sources are correct.

But if you have lots of cash coming out of the kazoo, anything can be done.
