Professionally installing new car radio?

I had recently just bought a 2006 Pontiac Vibe with the OEM stereo & I want to have an aftermarket radio that has a CD player with Bluetooth, Sirius XM & also an AUX input jack for my iPod/iPhone. That's all i'm looking to have done is a new radio put in. How much would it be to have it professionally installed?

What are the differences between the Droid Maxx and the Iphone 5?

I'm looking on whether to purchase the iphone 5, or the Droid maxx. The Droid looks more appealing to the eye, yet, are there any draw backs for it, as far as the technical aspect. What is better between each phone, and what do you believe i should purchase?

Will PS4 get NFL Sunday Ticket and other good apps?

I know it's not a "entertainment hub" like the XB1 but lets face it, it's 2013, it isn't all about gaming now. I want to enjoy some apps, netflix, NFL, ex. Will Sony put more and better apps on the PS4? And also, do you think they'll allow gaming recording and the ability to play music through it from (for example) your iPhone? And will they upgrade their camera to do better voice commands?

How to fix my iPhone background?

Is it worth it to buy the Apple Earpods?

I have an Ipod Touch 4g and have the original earbuds. I know that the new earpods come with the Iphone 5S. A lot of people say they sound a lot better, but are they really worth $29.99. I'm willing to spend it for them, but only if they sound good.

Do they have a lot better bass than the old model? I'm mainly looking for more bass.
