Finding the Denso headunit isn't the hard part... The real fun begins when you try making it play nice with the car, especially cars that were never designed for that particular headunit.bestbet to find the unit if not on ebay is carparts.com
i was searching and found some 2002 plus units for around anywhere from 550 up to 1500
and most junk yard will give a 3 months garantee on there parts so it wont be DOA
Actually, it's more like - "Oooh there's something I don't have, so I need to have it and I'm going to pay an arm and a leg to get just because there's a chance I can."Yeah thats true. Maybe its just for looks.
OEM is OEM!I would much rather have factory nav than those cheezy portable GPS units, for a number of reasons:
1). Radio volume is automatically lowered slightly during guidance instruction on factory nav, and returns to previously set volume.
2). Guidance with factory nav systems comes through directly through the audio system, which is much clearer than those tiny speakers in portable GPS units. Many portable GPS systems are nearly inaudible at highway speeds, and forget about if you have the radio on or are carrying on a conversation with passengers.
3). Radio volume is completely muted when issuing voice commands with factory nav.
4). Voice command activation is right on the steering wheel - you don't need to futz around with tiny buttons like with the portable units.
5). Factory nav screens are typically much bigger, clearer, and also change for day and night modes.
6). GPS signal pickup is usually better on factory nav due to the built in factory antenna.
7). In the event of GPS signal loss, the factory nav picks up the VSS signal and uses the internal gyroscope to keep the vehicle properly located. This is a big plus driving in cities with large buildings the keep blocking the GPS signal, rendering most portable GPS units are useless.
8). Do any of those portable GPS units have XM traffic?
9). Portable GPS units are an invitation for thieves to break in. Even if you hide your GPS in the glove box, or take it with you, if they see the suction cup marks on the windshield, your window is going to be smashed.
10). Bottom line is portable GPS is just a cheezy wanna be unit.
Yes, portable GPS units offer-up-to date road changes, but how often do roads change? If this was 1949, that would be important, but in 2009 there isn't much going on in terms of new roads.
I wouldn't go any other way than factory nav. Yes it's a few dollars more, and updates are somewhat pricey. But if you're that price sensitive, a Cadillac is really not for you in the first place.
They do play DVDs, stock. You just push a button and type a 4 digit code and it lets you view them out of park. The harness Jason "builds" repins the wires from the standard HU Bose plug to the unit, and has aux input jacks for video and audio. I still have that harness, in a parts bin.Dont those nav systems play DVD's? I think most people want them for that purpose more than the actual nav ability.
