Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Poor or no radio reception
  • GPS navigation losing signal frequently
  • Diagnostic fault code related to the module itself, if equipped

Installation information

Mounted near the antenna base, connecting to the antenna and the relevant receiving system via coaxial cable.

Frequently asked questions

A failing amplifier no longer boosts the weak incoming signal effectively, which becomes especially noticeable in areas with already marginal reception, like tunnels, car parks, or rural areas.

  • I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

  • No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

  • Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
