Hi, have a GPS Antenna Error showing on my Becker Traffic Pro (factory fit). As part of the headlining project I was hoping to simply reconnect / clean a terminal on the antenna and then get everything working. However, the connection (GT5) to the antenna at the rear seems fine, and has had a squirt of contact cleaner, but still no operation. I've also checked the connection to the head unit (WiCliC) and that seems fine too. So by process of deduction, I need a replacement GPS antenna. Unsurprisingly these are not available as an original part (Aerial Antenna XUI000070) or pattern.

Was wondering if anyone had found a suitable externally mounted alternative with a GT5 push-fit connection? I'd like to avoid butchering the loom, so if I can make the original connection work at the roof then perfect. Failing that, I'll have to run a new antenna with a connection all the way back to the WiClic connection at the back of the head unit.

I know there will be lots of "why not just replace the head unit / get a tom-tom" etc, but its more about having the original unit working and not showing an error message.

I'm also playing with a 3.5mm input jack adaption for music for the same head unit, so fee a little financial and emotionally invested in this!

Any support / ideas / hyperlinks would, as ever, be appreciated!

Several on ebay, but not in the UK. Not sure if this is just a patch antenna or if there is a gain stage in there too. Check on the car-side connection to see if there is 5 or 12v present on one of the pins. You might be able to find a substitute antenna for way less than the ebay jobs.

Thanks Spong, just making sure I understand your comment - if I run a mm across the Wiclic output from the headend I may see a voltage, suggesting that there is power as well as signal running to the antenna? I guess that way I can understand what I need to procure. I've seen a couple of GPS antenna with a nice big thread to attach to the body with the wire running through the middle of the thread/bolt (as per OEM) where I can specify the GT5 connection, but as you say these are in the US. A lot of the Wiclic are magnetic with a tail that may work, but not a good direct replacement.

Yes, I'm really just suggesting here as I've not got the GPS setup myself, and I haven't had much to do with it at work, but if there is a amplifier in the antenna housing it will need power such as 12 or 5V. The signal would then be sent back on the same conductor in the other direction, with the two being decoupled at either end. If you see something odd like 2Vish or less then you might just be looking into the front end of the receiver, so then the antenna is probably passive.

Roger, copy that!

5V at the WiClic on the head unit, 5V at the GT5 connection above the rear door... so head is apparently working, and connected through to the last leg at the back. I'll make the assumption (dangerous) that the head unit is fine (and not an internal error) and pick up a cheap antenna to verify. If good then I'll invest in some USD and gets decent external one sent over. Cheers Spong.
