Hey I have an 05 Corvette Base Model with the bose sound system and no nag system. I want to install the nav system that came with the vette. I was curious if this was possible, and how much it might run me.

 

Plug n play with the Bose. Get yourself the Nav head unit and the GPS antenna. You'll also need a dealer to program it so it works with your car once its installed.

There are a lot of used units offered for sale on the forum, much more reasonable than a new one.

 

Sorry newbie with this stuff what do you think about this in the C6 as opposed to stock OEM Nav system

Here's a comparison thread I did a while ago:

For us, the factory Nav works well. Go to "talon90" 's website and download his tutorial if you want to understand how to use the Nav, because it's not intuitive.

None of the aftermarket navs will give you the turn/distance readout on the HUD like factory. For me, that's a big deal. Others don't care.

I like the factory nav enough that i've never seriously considered replacing it with aftermarket. But if you need to buy something from scratch and install, then the aftermarket units become viable choices. Do your research first, and Google "xxx nav problems" for each brand. Some of them are good, some seem to be more annyoing than the factory setup.

 

Calling the C6 Navigation system non-intuitive is like calling King Kong a little monkey.

The C6 Nav sucks a big one.

Go aftermarket, you'll be happier.

 

My nag system is the Wife telling me I'm going the wrong way!

 

I can understand why some people don't like it.
But...
We have two "other maker" factory navs, two Garmins, and four cellphone navs. We've traveled many thousands of miles in convoy with people using aftermarket and portable navs in their cars. We've also had two C6's with factory nav, totaling eight years and 110k miles over most of the USA. I prefer our C6 factory nav over all the others we've used.
All of them will work, none of them are perfect.

 

Could you elaborate on pro's & con's of stock nav-vs-aftermarket nav

 

Pro's of using the factory unit,
1. anti theft, since as stated, the stereo has to be registered to the car via a Tech 2 tool, and that service is around $100 each time the radio has to be registered to a new car it being installed in.

2. The factory unit will display through the Hud system.

3. Depending on the year of the unit, it may or may not have USB into the radio.


Pro's of a aftermarket unit.

Blue tooth,
USB in,
Great Video quality graphics, and the ability to play DVD;s. Granted that the DVD thing for playing movies is good, it's where you download a DVD disc with mp-3 song files that it really starts to shine (read should be able to get 50 to 60 full music albums on a disc.
Back up camera input, and just a ton of more features that are not offered on the OEM unit.

As for the con's on the DVD, may not have an anti theft device, so does bring up the subject of more incentive for someone to break into your car to steal the radio.

As for the unit not displaying through the heads up, there is a company (might be Metra), that is working on a adapter to allow the aftermarket radio's to be able to display through the Hud system.

To be blunt, currently besides the after market radio not being able to display through the hud system (again, within a year and they will), The OEM Nav systems are decades behind the times in regards to features, and really offer no extra features that you find of most after market nav radio's. A Used OEMNav radio (that you have to take a chance it correctly working, after you have drop a C note to get it registered with the car) is going to run you around $400, another $50 plus for the needed items install it, then the $100 by a dealer to get unlocked/mated to the car. So best cause, you into the system for $550, and as stated, it pretty much a featureless system that will have you wanting more from it as soon as you install it.

So on that note, just keep checking until the Hud interface hits the market, and buy an aftermarket Nav system that has all the features that you want, including maybe even anti theft coding as well to make the radio less desirable to be stolen.

 

How much do you think an install price for an aftermarket navigation system would be and does it need anything done by the dealer? Registration or unlocking?

 

do it yourself. very easy. if you can remove the center console your good. Don't waste your money on the stock system. Too many new features to pass up

 

also Kenwood is a good for it's match with Garmin navigation, but there are others that are good

 

Is it really that simple, no saudering things together and stuff of that sort?

 

You will need the interface box to connect to the factory harness and bus. You could crimp the connections together between the interface and the harness of the radio is you can't solder.

 

Also check through the audio section and the FAQs at the top of that section.

 

If you buy from DoubleD he can prewire it for you. All you'll have to do is plug in the connectors.

 

Only the factory radio needs the Tech 2 tool to unlock a used radio so it can mated with a different car that is was not original installed in (the dealer $100 charge). The aftermarket radio will not need this.


Will second on talking with DoubleD, since chance are they will be the first to have the interface box model that will allow the aftermarket nav radio to communicate with the Hud unit when that interface becomes available.


As for the install, it pretty easy for the most part, but will touch base on the bose system since it is lacking over all from the amp to the speakers.


The only two speakers in the car that are not mono'd (have real stereo output) are the 3.25" in the doors. The center speaker and the even the rear speakers are mono outputs used for fill. Worst yet, there is no true tweeters in any of the speakers for clean highs, and a huge gap between very low base that the thumper's in the doors, and the low frequency base response of the 5.25" speakers in the back (read has no highs, has no lows, must be Bose).

Kicker has OEM replacement speakers for both the 3.25" doors and the back 5.25" speaker with real tweeters for around $100 to clean up/fill in the highs, and since the Kicker back 5.25' speakers and even the 3.25" to a smaller degree) have a better lower response frequency, it fills in the missing gap now in the system regarding the mid base to low base.


As for the mono rear speakers, I have not had a chance to pull a Bose amp apart to see the possibility of mod'g the amp to turn the rear speakers outputs to stereo, or not.

As for adding in another sub woofer off the amp, since the thumper's in the doors are not power driven off the amp (just get a signal for the amp, with the thumpers having there own amp), using the Bose amp for that source is a lost cause.

So on that note, although you may not want want to go buck wild down line of the head unit, do consider changing out the 3.25" and 5.25" speakers over to at least the kicker speakers. DoubleD has these in three flavors, and even includes the need wiring harness for the front speakers so you don't have to clip wires.


To add, who every you get the stereo install parts from, be very picky about the dash adapter piece. There are some that are more of finer softer sheen to them then match the factory plastic parts very well, while some have a more thinker pebble grain to the plate that make the plate stick out like a sore thumb instead.

 

Post #4 in this thread, has a link to the thread with the pros/cons list.

It seems like most people have their mind made up before doing any research. Every system has some real pros and cons, and the importance of those will be different for each of us. Read, think, and decide what's best for YOU.

 

The biggest current con of an aftermarket Nav radio is that it will not interface with the HUD.

As stated, I think that its Maestro that is working on programming it into the GM iDataLink to solve this problem, and just a mater of time before it hits the market.

 

And the biggest con of the OEM Nav is that it's as user friendly as a hand grenade with the pin pulled.
