Learn more about the ncgm39cThe Neucleus NC-GM39C is designed to be used in a non-amplified GM vehicle or in vehicles where the OEM Amplifier has been bypassed (OnStar will not be retained). This harness retains all the factory warning chimes that would be lost when the OEM radio is removed. It also provides a 3 Amp 12 volt switched accessory for proper radio operation and retain the RAP feature if equipped.
This particular radio replacement module retains the door chimes through the factory speakers, as opposed to the small built in speaker found on many other radio replacement modules. The chime volume is adjustable on select vehicles so it can be tuned to your personal preference. There are also 3 switchable Retained Accessory Power (RAP) modes. You can switch from Standard, to Extended, to Street RAP to allow for a 10 minute interval, a 20 minute interval, or finally a full 60 minute long retained accessory power! This means you can remove your key from the vehicle and still have accessory power for your radio for a full hour!

Easy to crimp to after market harness, anyone can do this after market hook up, not a novice with car audio but fits and works well with my 2006 chevy silverado ext cab ls. the r.a.p. works like the factory stereo, radio stays on after i turn engine off and radio turns off as soon as i open my truck door

This worked great on my 2005 Pontiac Grand Prix. Just make sure that you have a non-Bose and non-Monsoon stereo (i.e. Base model) or it won't work. Also, the front driver's speaker will quit playing music when the factory chime kicks in. This is by design from the manufacturer, as I contacted them regarding the issue.
All in all this is a great product for the price.
