I thought the difference in the numbers were for the RSE support. So, the nav units have a CD player or a DVD player in the slot on the face. Of course, the navigation dvd is placed behind the face in both.
I'll clarify for everyone a little bit.
For 2007+ SUV's / Trucks there are two main types of NAV units with many subdivisions, all of which work with each other if programmed correctly.
All types have a main break down: With rear seat entertainment or without. The main difference here is that the front disc play in the RSE unit will play DVD's when in park, or while in motion if you have the rear seat entertainment option. The non RSE unit will no play DVD's in the front drive. I believe every version of the radio has both of these options available. The following excludes Denali, Escalade, and H2 models.
Denzo makes the units that come in your standard truck and SUV (Excluding Escalade, Denali, and H2) and have blue lights. 2007-2008 do not have any serious differences that I am aware of. 2009 is compatible with Bluetooth (it does not control the blue tooth, that's the VCIM, but it is compatible). 2010-11 have an option for a USB drive. Any of these will work in a LAMBDA model as well but did not come stock from the dealer and you may confuse them when you come in for programming, but they 100% will work. These require the Denzo discs, so make sure if you install a Denzo unit that you order a disc for a Silverado Tahoe Sierra ETC.
Delphi makes the unit that comes in the LAMBDA models. They are all the same except have different colored lights. Acadia has red, Outlook is kind of whiteish-yellow, ETC. 2007-2008 seem to be more or less the same. 2009 are compatible with Bluetooth but do not control the Bluetooth (this is in the VCIM) 2010-2011 have an option for a USB port. Any of these will work in a LAMBDA model (or a standard NBS truck model) but again, your dealer may look up the part number and get confused, but they will absolutely work. These require the Delphi disc, so make sure if you install a Delphi unit that you order a disc for a Acadia, Outlook ETC.
All of the above will also work in some other models, but I’ve only personally tested them in SUV’s.
If you are putting any unit into a LAMBDA, you will require the head unit, NAV Antenna, and disc. If you are installing a 2009+ unit and want Bluetooth, you need a VCIM as well. If you are trying for USB, you need a little bit of custom wiring for an input and the USB wire. No VSS wire is needed, it already exists in your vehicle.
If you are putting any unit into a NBS Truck / SUV, you will require the head unit, NAV Antenna, and disc. If you are installing a 2009+ unit and want Bluetooth, you need a VCIM as well. If you are trying for USB, you need a little bit of custom wiring for an input and the USB wire. A VSS wire is not required, but is recommended.
Any used unit you purchase should be theft-locked, and will require the VIN from the previous vehicle for the dealer to unlock it.
Any NEW unit shouldn’t need to be unlocked unless someone unfortunately powered it up in another vehicle for some reason.
The install is relatively painless. The unit will work without programming, but you may experience some… Unpleasantness, as your door chimes and turn signals will be very loud, and not all of your features (XM, steering wheel controls) may not work. This can only be solved by taking it to a dealer and having it programmed. The problem is some dealers simply don’t know how to do this. For this reason, I recommend that if you are going to do the upgrade, use Google, get a list of a few local GM dealers (doesn’t need to be your make, any GM dealership will do) and ask their service department “Have you upgraded a truck without navigation to one with navigation before?” if you say no, call the next one. If they say yes, you should feel somewhat confident about taking it in to them.
If you take the unit in and they tell you it won’t work based on the part number, they’re technically correct (their system may indicate that it doesn’t) but the reality is they do work. Take it somewhere else if they won’t do it. If they do the programming and can’t get it, they’re programming wrong and don’t know how to do it properly. If they do the programming and it doesn’t work correctly (or the chimes are still loud) they did it wrong and need to do it again and be more careful entering your options.
If you still are having problems, e-mail me at firstname.lastname@example.org
. I have step by step directions on how to do it, but even with these some dealers still fail. I have no explanation why, but usually the best (and only solution) is to take it somewhere else.
If you want to avoid this, I know there is a company out in California that does the programming on a bench. He charges about the same as a dealer would. But from what I understand, he cannot program a Denzo unit for a Delphi vehicle or a Delphi unit for a Denzo vehicle., so if you’re going to go that route be careful.
I think that about covers it.
