You just need to connect the power cable from us to Pumpkin unit, and please notice, the Canbus box should be connected, otherwise the unit will not turn on, cause the unit is turned on by the Canbus signal which need to decoder from your car Canbus system.


There are three connector from one side of the special extension cable. We mark them with three number in order to make the connection easily to be understood.

Before you connect these three connector to your car, you first need find the unit under truck of your car, then connect the corresponding plug correctly.


Normally if your car is right hand driver mode, you can find the unit under the left truck, please refer to the attached picture. The left hand driver car has the unit under the right truck.

The NO.1 plug is used for Canbus signal output from your car to our unit.

The NO.2 plug is used for providing power for the unit.
The NO.3 plug is used for directly connect our four couple speaker wires to your car speaker.

Please notice:

-Bold Yellow Wire need to connected to your car battery to get 12V permanent power supply
-Red Wire 12V should be connected to your car ignition (ACC) wire
-Bold Black to Ground


If your car has canbus system but you bought our universal unit, you may need to buy the adapter or modify wires to make our unit work with your car.


For some special car, such as Nissan, which original ISO cable does not have ground wire, you have to connect the radio antenna（it’s peripheral metal parts can be nagetive pole) as the negative connection which form a circuit to make the unti get power supply.


Then check at the power harness both on the radio side and other Car connector side.
Please make sure power harness on the radio side connected tightly and the blue fuse in the back of our unit.
There are some unit which need to be turn on with power button, not all the unit turning on when you start the ignition key.
A few case which the stucking button also result the unit not turning on.


If you exclude all these possible situation, you may need to remove the unit from your car to test if the red and bold yellow wire have 12V-14 V power suppply.
You can also install your original radio to check if it’s the power supply problem or the power cable problem.
Here is a tutorial video for your reference.

Situation 2:


For the specific head unit which have power cable with canbus box, such as VW, BMW, Benz etc..
Some car which have canbus system control original radio turning on and off, then when you buy the unit from us, our unit will also canbus box to decode the ignition signal come from the car canbus system.
If the canbus box have problem, then our unit can not be turn on normally. Under this situation, you can remove the canbus box, then cut the red wire and join it into bold yellow wire, or refer the below picture using a extra wire to connect the red and yellow wire

If the car stereo can be turned on with this wire modification and your car car don’t have steering wheel control or you don’t mind the steering wheel control, you can just connect the red wire to your ignition ACC wire, then you can continue to use the unit.
Or we can send you a new canbox to solve the problem.


If the car radio still does not turn on, the unit have problem, you may contact our customer serivce to return.


Situation 3:

The Pumpkin Andorid Single Din Car GPS DVD Player we’re talking about is: goo.gl/FHnq9e

This is a full-blown Pumpkin android tablet for your car. It’s well built, well thought out with great features, and generally well polished. Google Play is included, so you can just install apps from the play store (although you’ll really need an SD card and will have to move as many apps to it as possible). Most apps just work, and work great. Apps that want a lot of space on internal flash storage (such as Google Maps, for its offline maps feature) may have major problems. It’s not ENTIRELY stock android: one third-party app told me change a setting in preferences, opened the preferences for me, and the setting wasn’t there. Mostly though, the changes are to add features, rather than remove features.


Sound quality is good. Radio tuning and quality is decent, though it seems to only catch main stations — maybe the stereo (ST) or local (LOC) settings will help it tune more distant/weaker stations, but I haven’t tried those yet. Some volume tweaking is required to make the navigation volumes sane whilst also listening to music, but I think it’s customisable enough for that to be OK.


Haven’t tried the DVD video/audio playback yet. For a linux/phone hackery-type like me, though, this is doing everything I really hoped for so far, apart from the storage and DAB issues, which are mostly surmountable.


Also, I didn’t expect this, but if you connect your android 6 phone with USB and use the Easy Connect app included, it will prompt you to enable USB debugging / mutual control, and then your phone will become a secondary Android Drive mode screen. So between this, your (modern) phone, and a car mount, you get TWO computerised driving displays


Highly recommended, if single din is all you have.
