DIY - Before you order a new NAV DVD for X5 (Hualingan)

[nezarnuaimat]

Hello Guys,

Just bought a Hualingan 4th generation from eBay and installed it on my 2002 E53 with Navigation screen, no DSP.

I thought to share my experience with you guys. There are some important steps you need to do prior to ordering, so that you don't need to cut and splice wires, and you get a plug-and-play part.

Please read below before you order it.

Here's my original unit:




Here's what I did in order to get a plug-and-play unit:

1- I first checked the back of my OEM unit:






It would need a 5m long cable from the trunk to dashboard. These cables can have either 17-pin or 40-pin plugs, so

2- I checked my trunk under the spare wheel:





I found this plug. Counting pins it's 17:


3- So, I ordered an extra 5m long cable with the old 17-pin plug.
4- I ordered GPS maps for my country
5- I ordered the optional MPEG-4 DVB-T (digital TV)

I got my box two weeks later.

Here's the new unit as appears in the adv:

Built-in GPS navigation receiver system
7.0 inch 800*480 digital HD touchscreen

Maybe the software is also for portable-units that operate on batteries.
Since your unit has power from the car and has no further portable capability these 'bars' will stay as you show above as 'empty'.

Hope this makes sence in some way

it dont make sense because i had the same unit before and it had all the lights on... unless it is because of the 2 wires i didnt hook up i didnt know where they go the brown brake wire and then another wire i cant remember if its orange or pink but yeah i dont know where those 2 hook up too

So did you get it working properly, how do you like it?

[cuban_bmwx5]

Hey Guys, I connected the new radio wire to the antenna wire that was originally plugged into the original RCM (radio control module), but the sound jams and there is interference. Any ideas where/ how to connect the new antenna?

[nezarnuaimat]

Now my radio works very fine.

I connected the TUN-ANT (BLUE) wire to +12 V (red wire in the new 5 m harness), and then I cut both OEM radio antennas (looks like one is AM & one FM), and connect then to the new antenna wire.

I installed my Hualigan GPS Antenna inside the dash on top of the tubular steel support. Not getting the best signal strength with a few brief loss of signal during cloudy weather. I;m thinking of re-positioning and or moving to the rear of the Vehicle,

Has anyone run into similar situation.

They also sent me a NTSC Digital TV antenna with magnetic base. I get zero signal with this antenna installed inside dash. Looks like I will need to run this one to the rear of the vehicle as well.

Cheers

I bought a hualingan head unit from the factory in china, it says car audio on the box not the name, I gave them all the info for my car (year model, DSP, SAT etc), they said I got everything I needed to do the install but I notice I did not get any 5M cable, do you think I need it? I have a 2006 x5 3.0 w/o DSP but I have sirius and navigation.
