How to unlock frequency step (from 0.2 MHz to 0,05) in Alpine ida-x303? That is how to enter in service menu?

It doesn't work! The Radio is from US and frequency step is 0.2MHz in ALL(!) searching modes. It doesn't work! The Radio is from US and frequency step is 0.2MHz in ALL(!) searching modes.

Radio is from the US and its frequency search uses only odd frequencies ex.: 89.9--90.1--90.3--90.5--etc.
How to switch tuner to work with European standart? (89.9--89.95--90.0--90.05--91.0--etc.) Radio is from the US and its frequency search uses only odd frequencies ex.: 89.9--90.1--90.3--90.5--etc. How to switch tuner to work with European standart? (89.9--89.95--90.0--90.05--91.0--etc.)

Thanks, but what should I do with setup menu? There no anything to solve my problem. I need make European standard radio from US. For this purposes is the special service menu or it is need to reinstall some components on the main PCB. How to get service menu I don't know, and I haven't got wiring diagram to make changes.

Did anybody something like I need before? Did anybody something like I need before?

You are 100% understood what I need. But, unfortunately, IDA-X303 hasn't got any switches (except one on the bottom side - for use external controller) by which I could solve my problem. So or it special service menu or some components on PCB.

I need make from US radio Europe radio on my Alpine IDA-X303 I need make from US radio Europe radio on my Alpine IDA-X303

Unfortunately, there aren't solving my problem in that manual (I've already got it). Previous expert understood completely what I need. Thanks. Unfortunately, there aren't solving my problem in that manual (I've already got it). Previous expert understood completely what I need. Thanks.

How to make US radio to receive even frequencies?
Have: 89.9-90.1-90.3-etc. Need: 89.9-90.0-90.1-90.2-etc. How to make US radio to receive even frequencies? Have: 89.9-90.1-90.3-etc. Need: 89.9-90.0-90.1-90.2-etc.

Thanks, but it isn't solution.
You are wrong about that it is impossible to change. Models for US and Europa are same by their hardware. There is a way to switch it, but only Alpine specialists know how. They don't say, unfortunately. Thanks, but it isn't solution. You are wrong about that it is impossible to change. Models for US and Europa are same by their hardware.

Thanks. But I am sure that US receiver and European are the same by their hardware. Of coarse, it is possible they have their own firmware. I think the manufacturer isn't stupid and left a way to reprogram unit with new firmware without replacing ICs. All that I need to find how to do it. Thanks.

I've got receiver from US and its frequency step is 0.2 (89.9--91.1--91.3--etc) I need freq. step as at unit produced for Europa 0.05 to have possibility to turn on even freq.
