Sean McVeigh of Victoria Street in Lurgan was charged with attempted murder and possessing Semtex with intent to endanger life on June 18 last year.
McVeigh did not acknowledge the court and refused to stand.
When asked did he understand the charges he sat in silence.
A defence solicitor Mr. Peter Corrigan said there would be no bail application but they were challenging some aspects of the connection.
He said the evidence against McVeigh was allegedly 'low level RDX detected in clothing after his arrest in the Republic of Ireland.'
The solicitor said there was no conclusions in the reports or expert evidence. He added that CCTV being used as regards a vehicle McVeigh was allegedly in did not in any way connect him to the incident in Eglinton in June.
The solicitor said there was no DNA or fibre evidence connecting his client to the scene. He asked for disclosure from the prosecution so a full bail application could be made.
District Judge Barney McElholm said that anything that could be disclosed should be and remanded McVeigh in custody to appear again on May 16. As he was being led from the dock supporters in the public gallery applauded.
