Absolutely First Class service from Revtronic. I posted my Mercedes Becker Map Pilot to Revtronic in Bradford on Monday 24th February. The map pilot was frozen on the Becker logo, Mercedes main dealer couldn’t fix it despite them having my car for 6 hours and charging me £70 for a diagnostic examination. Revtronic returned my Becker Map Pilot to me at noon on Thursday 27th February duly repaired and in full working order. I couldn’t recommend this service any higher, brilliant.
