I recntly replaced my factory radio with a new Kenwood that has nav, satelite, backup camera, dvd, etc....
The problem I'm having is the backseat radio no longer works.
The installer told me that it won't because I took out the front factory radio. Has anyone had this issue, and if so, what did you do to fix it?

Nope. Rear seat radio is dead without the front HU. The front HU is the "brain" for the rear seat controls.

I took mine out and threw a small screen in there. Not that it's really intended for watching, I just think it looks a lot better than some controls that can't be used.

Supposedly the Meta GMOS-14 allows you to keep the RSE. I'm not sure what the limitations are. The manual doesn't really describe what RSE capability the GMOS-14 provides.

I will be putting a Pioneer AVIC-Z130BT and using the GMOS100. I don't care about the RSE because my rear dvd player and tv screens are aftermarket. I will be able to wire the Z130 directly into rear screens.

i will definitely post back with pics and a complete write-up as i didn't see alot of details on here specific to aftermarket radios. i'm just waiting on the GMOS100, antenna adapter and dash kit. hopefully i won't lose rear hvac control. if not, no biggie...passengers will just have to suck it up and let me control the temps.

i'll also post up a complete write-up of a compustar + drone mobile install (complete w/autofold mirrors on arm/disarm). i'm just waiting for the ads-blade al.

you will still have it in the front so you will be better off just putting the control to auto and just adjust the temp it may not the range the rear controls would give cause it is like the front driver and passenger controls in the front that goes form 60 to 90 on the temp range you ain't losing much anyway but nice screen beats cutting up the headrests on the front seats to put screens in them

I honestly never even thought about rear HVAC controls until I just read that. I have kids, so I control the temp up front anyways. I also have a roof mounted flip down screen. The seat heaters still work fine. Like I said, I did this to get rid of that other piece that I wasn't gonna be able to use anymore.

I kept the factory nav and installed an additional indash monitor for entertainment. She can watch movies, I can keep track of where I'm at in harmony lol. I still have the controls in the rear HVAC and Radio, but no sound comes from the rear head phone plugs.. (weird). But the rear overhead monitor has it's own built in DVD player, and wireless head phones. I probably could find an adapter that would make the head phone jacks for the radio (rear ent center) work again, since the factory head unit is still connected. Never thought about it till I read this post yesterday and tried to get the radio to play through the head phones. The heater controls work and I can change radio stations with the controls.. just no sound through the head phone jacks.

try all of the sources if it still don't work it might have to be replaced if you have the rear seat dvd system try using it with the rear audio controls to see if it works if this don't work i would say the headphone amps in the unit is bad cause it should since you didn't remove the factory radio which would mean the rear seat audio controls will have to be replaced

The rear overhead monitor is aftermarket too. I used the rear controls to cycle through Sirus, HD and regular radio. No sound but it scans channels and functions properly with the HVAC controls. I'm sure it has something to do with the aftermarket headunit installed up front. There's probably another adapter I can have installed, or have something reconnect that was looked over by the installers.

if you used the stock wiring with the aftermarket radio you lose the rear seat audio controls completely even though some places say they will still work
btw how did you hook up the second radio???

i don't think that there is a way to integrate a aftermarket dvd player to the factory controls the stock rear seat dvd system works in with the rear seat audio controls on the rear of the center console that is how it is on mine

My aftermarket Head unit runs through my Factory nav... I still use the volume controls from my factory NAV to control the aftermarket unit. I can unplug the harness and everything is back to normal, but my aftermarket unit won't have sound. The door panels are large enough to put four more speakers in them. (I have four speakers in the front, thought I could install an extra set of speakers to the factory nav, so it would have it's own set of speakers and the aftermarket could use the existing bose speakers but the bose system complicated that idea. not possible). One day I just might, maybe reconnect the factory nav to the door speakers (remove harness) and have a completely new set of speakers installed for the aftermarket headunit (have them run from an amp to components). I have more ideas than ways to finance them at the moment lol. I'll go outside and take a picture of the front panel and my hidden switches in a sec, might help to understand all my gibberish.

Did some editing cause I didn't even make sense to myself after reading it.

The second set of speakers where going to be installed for the Factory Nav, so I could still use the voice nav playback. (They tried,didn't work)

Nav stays up the entire trip at all times.. And the passenger just watch a movie (and let you just listen to the engine) lol

One in the rear playing for the kids (So, they don't have to watch what is playing in front)

Left switch (toggle the ground, Play in motion or not) Right switch (toggle sound for factory nav on/off) didn't work

headsets incase.. incase I say so!

front and back play different movies. aftermarket unit has zones, front and rear can play different inputs at same time (speaker sounds too).

Everything is functional but the sound doesn't come through the headset jacks. (big deal)
