Looking for a reasonably priced aftermarket radio and install kit wuth Bluetooth. Currently have factory NAV unit, but dont need the NAV. Just something that works better than U-Connect!
Replacing the uConnect head-unit with a decent aftermarket receiver that has BT capabilities is easy. There are dozens of options that you could go with and not spend more than $250 for whichever one you choose. HOWEVER, making that aftermarket receiver work in your car while retaining all the current functionality like steering wheel controls, etc. will cost you.
At the very least, you'll need the main wiring adapter kit to interface the aftermarket unit into the car's electronics. The Metra 99-6514B Radio Replacement Module is such a kit, and it'll run you about $400, give or take...
You'll likely want to keep the ability to listen to local (terrestrial) radio, which means getting an antenna adapter. The Metra 40-EU10 antenna adapter is such a device, and it'll run you $10-15 or so IIRC.
If you have steering wheel controls, and you want to retain them, you'll need an adapter for that. The Metra ASWC-1 is such a device, and it'll run you about $50-60 IIRC.
There are other adapters you will need to acquire if you have other needs, e.g. retaining the use of a factory amplifier, and they'll obviously require even more money to be laid out in addition to the cost of the head-unit. Crutchfield.com is an invaluable resource for finding all those items and identifying them (even if you do not buy from them), so I recommend spending some time doing research there if you're serious about moving forward with this upgrade.
